The mention “WS” (WATCH-SECUR™ Abbreviation) followed by an alphanumeric code of 9 characters, corresponds to a new generation serial number for Tissot watches. The code, secured by an algorithm, held exclusively by Tissot, allows the brand to trace the watches individually from the production in Switzerland to the delivery in the official points of sales of certain countries. All the watches produced as of 2016 possess a WATCH-SECUR™ serial number.
Functioning of the watch
The accuracy of the watch depends on the movement and individual habits of the wearer. The majority of mechanical watches (excluding certified chronometers) have average precision tolerances of between -10/+30 seconds per day. To earn the title of chronometer (see question relating to chronometers), the mechanical movement's average precision must be between -4/+6 seconds per day.
The precision tolerance of quartz watches is around -0.5 to +0.7 seconds per day (excluding certified quartz chronometers). Exposure to significant variations in temperature can have a slight effect on quartz movements.
The power reserve of a self-winding watch depends firstly on the type of movement. When fully wound, the movements of our watches have a power reserve of between 36 and 80 hours. The power reserve also depends on the wearer's individual habits and activity. As an indication, 10 to 12 hours' wear should be sufficient to generate a power reserve of 20 hours or more, which ensures that the watch will continue to run throughout the night.
A chronograph is used to measure time which has elapsed from a given moment. Its uses include timing the duration of a sporting event using the chronograph hand, accompanied by minute and hour counters. A chronograph therefore has two independent measuring systems: one to indicate the time and another to measure short periods of time.
A chronometer is a high-precision mechanical watch, which has been awarded an official certificate by the official Swiss chronometer inspectorate (COSC). Chronometer movements undergo precision testing for 15 days and 15 nights in various positions and at different temperatures, as well as water resistance tests. To earn the title of chronometer, the mechanical movement's average precision must be between -4/+6 seconds per day.
It is therefore possible for a chronograph to be a chronometer, but only if it has been awarded the certificate by the COSC.
A quartz watch can also be certified as a chronometer by the COSC. For this, the movement must strictly be equipped with an electronic system to offset variations in precision caused by temperature changes. Quartz chronometers are tested for 11 days in one position and at three different temperatures. Quartz chronometers are up to 10 times more accurate than a standard quartz watch (± 0.07 seconds per day).
Tissot watches are designed to be water resistant to a pressure of 3 bar (30m/100ft), 5 bar (50m/165ft), 10 bar (100m/330ft), 20 bar (200m/660ft) or 30 bar (300m/1000ft), as indicated on the case back.
Watches are pressure tested in a laboratory by means of tests conducted at various pressures corresponding to the pressure experienced by a swimmer or diver sitting still at various depths. However, many water-based activities involve a lot of movement and other environmental changes which exceed the boundaries of the tests conducted and may therefore affect the water resistance of a watch.
A watch's water resistance cannot be guaranteed indefinitely, as it may be affected by ageing gaskets or an accidental impact to the watch. As stipulated in our Watch care section we recommend that you have the water resistance of your watch checked once a year by an approved Tissot service agent. We also recommend that you do not under any circumstances open the watch yourself and do not adjust the time-setting crown and/or pushers (buttons) when your watch is underwater. Similarly, check that the crown is in position 1 (pushed in) or screwed down (depending on the model) before you enter the water.
Precautions for use and care advice can be found in the Watch care section. In addition to that advice, we also recommend having a service carried out every four to five years by a Tissot-certified service centre.
Both types of movement are mechanical movements, but are wound in different ways. Manual-winding watches must be wound every day by hand using the crown, whereas self-winding watches are wound by an internal rotor which responds to wrist movements.
A Lépine watch does not generally have a cover and the crown is at 12 o'clock.
A Savonnette watch meanwhile does generally have a cover and the crown is at three o'clock.
Autoquartz movements combine the advantages of a quartz watch and a self-winding watch. If worn for 60 to 80 days, the movement reaches a maximum power reserve of 100 days. It offers the precision of a quartz movement and functions without a battery, instead having an accumulator which recharges automatically from the movement of the wrist. The swinging movements of your wrist cause an oscillating weight to rotate. Each of its rotation activates a micro-generator which in turn charges an accumulator with electrical energy.
On a watch, a tachymeter is used to measure average speed over a given distance. To be specific it is a chronograph with a graduated scale on the dial or the glass, on which speed can be read off in kilometres per hour based on a 1000m distance.
To read the tachymeter, only the chronograph's central hand is used. Start the chronograph and stop it once 1000m have been travelled. You can then read off the speed indicated on the dial by the chronograph's central hand. Example for calculating the speed of a car: the chronograph indicates that the distance of 1000m has been covered in 30 seconds. The chronograph's central hand indicates 120 on the tachymeter scale. The average speed over 1000m is therefore 120 km per hour.
A bezel is an adjustable ring on the case, often used to record additional data, such as the duration of an event or to read the time in a second time zone. A bidirectional bezel can rotate in both directions, clockwise and anticlockwise. A unidirectional bezel only turns one way to prevent it accidentally turning in the wrong direction and therefore giving a false reading. When measuring diving time, for example, any impact or false manoeuvre can only reduce the pre-set limits, preventing the user from having an exaggerated interpretation of air or decompression time.
To use a unidirectional bezel for deep-sea diving, place the bezel's main indicator (initially positioned at 12 o'clock) at the projected time for the end of the dive. When the minute hand meets the main indicator, the diving time will have been reached. For example, for a 30-minute dive starting at 15:00, align the bezel's main indicator with 15:30 (at six o'clock) just before diving. The minute will take 30 minutes to reach the bezel's main indicator, thereby indicating remaining diving time.
This function allows the chronograph to be reset to zero without having to stop the chronograph first. This is often used in aviation, where several legs of a route are flown for specific periods of time in sequence. It saves time by beginning timing of the next leg without having to stop, reset and restart the chronograph.
Why is the Roman numerals indicating four o'clock on my watch represented as IIII when the correct figure is IV
Two ways of writing the number 4 are admissible: IV and IIII. There are various historical explanations for this. It is known that IIII was used for over four centuries, to avoid confusion between IV and VI when the watch is upside down. Another theory has it that in the 16th and 17th centuries, IIII was used to make it easier to read the time for people who were illiterate. Finally, it can be seen simply as an aesthetic choice, since IIII representing a better balance with the VIII opposite.
A "partial" service consists mainly in a battery replacement for quartz watches or an adjustement of the rate for mechanical watches. In addition, the replacement of spare parts guaranteeing the water resistance are also included in this service. A service becomes "complete" when interventions on the movements turn out to be necessary (replacement of worn components and oils). All operations of the partial service are also included in the complete service.
My watch has stopped. I took it to a retailer to have the battery changed. I just received the estimate from the Boutique, who is suggesting a complete service. Why?
To determine why a watch has stopped, a thorough analysis of the watch is required. A quartz movement - like all type of watch movements - has to be serviced regularly. After a thorough analysis, the authorized watchmaker can determine why the watch has stopped as well as identify the appropriate maintenance.
All servicing of your watch must be carried out by one of our authorized service centers. Any service not carried out by an authorized service center will void the warranty. A complete list of service centers is available in the Customer Service section.
Like any high-precision instrument, a watch needs to be serviced regularly to ensure optimum functioning. The servicing frequency depends on the model, the climate and the care you take of it. As a general rule, we recommend that you have a service carried out every four to five years by a Tissot-certified service centre.
Servicing of your watch depends firstly on the availability of its components. From the date production of your watch ceases, we guarantee the availability of spare parts for a minimum of 10 years, and up to 20 years for gold watches. If production of a particular part is haltered or suspended for any reason, we reserve the right, at our sole discretion, to offer an alternative solution. We will also do our utmost to maintain collector's pieces and jubilee watches.
The prices indicated in the Customer Service section should be considered as indicative. This is because the law in many countries prevents the imposition of retail prices. Each independent authorized service center is therefore free to set its own service prices. The recommended retail prices stated on this site are nevertheless valid in countries with an official service center belonging to the Swatch Group Ltd.
Battery life usually varies between two and five years depending on the type of watch, its dimensions and the amount of energy required by its various functions. For example, a watch whose chronograph is activated continually will have a higher energy consumption than a watch which only displays hours and minutes. Most Tissot watches have a battery EOL (End Of Life) indicator. When the second hand begins to jump every four seconds, it is time to have the battery replaced by a Tissot-certified watchmaker.
All our watches are covered by a 24 month sales warranty from the date of purchase.
The warranty conditions are provided in the warranty booklet supplied when the watch was purchased or in the Customer Service section.
Services carried out by an authorized service centre are covered by a 24 month service warranty on the work carried out. This warranty does not cover normal wear and tear and damage caused by accidents or lack of due care. This warranty is void if any work is carried out by a third party that is not authorized.
Only service centres meeting the strict criteria relating to equipment and technical skills are supplied with original Tissot spare parts. This allows all customers to enjoy a service in line with Tissot's standards of excellence.
Magnetic fields: Do not expose your watch to intense magnetic fields such as loudspeakers or refrigerators and other electromagnetic appliances.
Shocks: Whether thermal or other shocks, avoid them. In the event of violent shocks, please have your watch checked by an authorized service center.
Crown: Depending on model, push or screw it in carefully to ensure that no water enters the mechanism.
Cleaning: For metal bracelets and for all water-resistant cases use a toothbrush with soapy water and a soft cloth for drying.
Chemical products: Avoid direct contact with solvents, detergents, perfumes, cosmetic products etc., since they may damage the bracelet, the case or the gaskets.
Temperatures: Do not expose your watch to sudden temperature changes (exposure to sunlight followed by immersion in cold water) or extreme temperatures over 60C (140F) or under than 0C (32F).
In the wake of the Covid-19 coronavirus pandemic, hygiene precautions need to be stepped up in everyday life.
The same applies to your watch. Below you will find our tips, which can be followed alongside strict hygiene measures, such as washing your hands frequently.
On parts made of metal, silicone, plastic, sapphire (the watch crystal or the back of specific watches):
Wipe with a lint-free wipe impregnated with a hydro-alcohol solution, usually based on methylated spirits (a solution containing over 70% alcohol).
Be sure to concentrate on the moving parts (e.g. bracelet links) and uneven areas.
Then leave it to dry, without wiping the watch. The wipe is disposable and must be thrown away after use.
For leather, rubber, cloth and plastic straps with decoration, as well as polymer watch crystals or case backs :
Wipe with a lint-free wipe soaked in water with a little soap added. Avoid using an alcohol solution, which could cause permanent damage to these materials.
Be sure to concentrate on the moving parts (e.g., bracelet links) and uneven areas.
Then leave it to dry, without wiping the watch. The wipe is disposable and must be thrown away after use.
These measures cannot entirely guarantee a level of disinfection that is capable of eradicating viruses and germs, especially on delicate materials that cannot be cleaned with an alcohol solution, such as leather. However, they will make a contribution to maintaining a hygienic environment.
The high-quality stainless steel (316L) used by Tissot belongs to category 1.4404. Tissot watches are subject to rigorous quality tests which exceed European and international standards, particularly in relation to standard EN1811:2011 on the release of nickel. However, if you are allergic to nickel, we recommend you buy a watch which is made of titanium or gold or which is PVD coated.
PVD stands for "Physical Vapour Deposition". It is a process performed under vacuum which deposits microscopic particles on the products by ion bombing or sputtering, to form a protecting coating on their surface with a specific colour. Very thin layers (1 μm) of impurity-free components can be obtained which possess high levels of hardness and hypo-allergenic qualities.
Titanium is a metallic element found in the earth's crust. The element occurs as a bright, lustrous metal or a silver-grey or dark-grey powder. Titanium is 50% lighter than steel and very corrosion-resistant. When exposed to air it forms a hard oxide film which resists corrosion and salt water. Titanium is hypo-allergenic since it is nickel-free.
Radium was abandoned by Tissot in the 1960s, followed by tritium in the 1990s. No watches containing radium or tritium have been produced by Tissot since then. Tritium was replaced with a new luminescent material called Super-LumiNova, which is used in the manufacture of our dials and hands. Super-LumiNova is phosphorescent only and consequently has no radioactivity whatsoever. It takes its luminescence from daylight or any artificial source of light. The watch should therefore be exposed to bright light in order to ensure the luminescence of the dial and hands in the dark. The luminescence decreases with hours but it is restored as soon as the watch is exposed to bright light.
The indication "T Swiss made T" (usually printed on the dial face at six o'clock) means that the watch is Swiss and contains a certain quantity of tritium that emits less than 227 MBq (7.5mCi). It is important to specify that this radionuclide emits a radiation of low energy, perfectly confined by the watch case and glass. Under no circumstances will they threaten the health of the wearer.
In rare cases, tactile watches may become out of sync. There are various reasons for this, particularly violent impacts or magnetic fields. The hands can be synchronised at any time by following the instructions contained in the user guide, available in the Warranty and user's manual section.
In the cabin of a plane in flight, the altitude indicated by the T-Touch Expert will no longer be accurate. Why?
Airline cabins are pressurised for safety reasons. Since the altimeter bases its data on the ambient pressure, the altitude displayed will not correspond to the pressure outside the plane.
What influence does setting the hemisphere and climatic region have on the functions of tactile watches?
These settings, which concern average temperatures and relative pressure in your geographical location, allow a more accurate calculation model to be used for the weather, altimeter and altitude-difference metre functions. The calculations are also adapted for the seasons.
I went on a walk where the altitude fell from 1200m to 600m. Why does the altitude-differenc metre on my watch show that I descended 800m?
From its activation, the altitude-difference metre adds positive and negative altitude changes using an atmospheric pressure sensor inside the watch. It is rare for the wearer's route to ascend or descend at a constant rate. Small ascents or descents in the route are therefore added to the total theoretical change in altitude, potentially leading to significant discrepancies. So if the route begins at an altitude of 1200m and ends at 600m, it is highly likely that the route itself represents a cumulative descent of 800m.
What is the difference between water pressure and air pressure and how does Sea-Touch calculate my depth?
The Sea-Touch uses water pressure to indicate your depth. The watch measures absolute pressure (quantity of air in a specific location) at the surface and uses it as a reference to calculate subsequent variations in pressure.
On Earth, a pressure difference of 1 hectopascal (hPA) corresponds to a change in altitude (increase or decrease) of around 10m. Under water, a difference of 1 hPA corresponds to an increase or decrease of around 1cm in depth. That represents 1000 times more pressure! Measuring air pressure is therefore totally different from measuring water pressure. That is why we use bar units to measure water pressure (1 bar = 10m). Pressure sensors present in most tactile watches do not have the same sensitivity as Sea-Touch sensors and so do not allow calculation of water depth.
It is not possible to erase dive profiles. However, a Tissot-certified service centre can do it for you. A complete list of official service centres is available in the Find a Service Centre section.
The number of dives which can be stored is directly dependent on their average duration. On average, up to 99 dive profiles will be stored. Once this number is exceeded, the oldest will be replaced by the most recent.
A scuba diver does not generally descend lower than 60m. Tissot guarantees the accuracy of the depth meter up to 59m. Beyond this limit, the diving mode is blocked to protect the diver and prevent the sensor from being damaged by excessive pressure. If this limit is exceeded, a small spanner icon appears in the LCD display. Please also be aware that below a depth of 30m, most insurance policies no longer cover you in the event of an accident.
The little spanner means that the watch has experienced an error and needs to be checked by a Tissot-certified watchmaker. A complete list of official service centres is available in the Find a Service Centre section.
The precision of the depth meter is in line with European standard EN13319, which tests the reliability and effectiveness of diving products. The precision depends among other things on depth and weather conditions. Up to 3m: +80/-40cm. Beyond 3m: +80cm/-1.5m.
Before each dive, the Sea-Touch checks all the functions of the watch and the battery level.
If one of the tests fails (e.g. the battery level is too low), the watch prevents activation of Dive mode, to protect the diver from an accident due to incorrect interpretation of data.
One of the rubber protectors for the pushers on my Sea-Touch is broken. Can I still dive with my watch?
Yes, but to avoid a build-up of salt on the pusher, we recommend immediately having the rubber protector replaced by your nearest Tissot-certified service centre. A complete list of official service centres is available in the Find a Service Centre section.

Some models of telephones have manufacturer's specifications that make them incompatible with each other:
Xiaomi M8 Lite
Blackberry Key 2 LE
Samsung A21 S
Iphone 6 or lower may present instabilities
If you are experiencing problems specific to a particular phone model, please let us know.
To connect your phone to your T-Touch Connect Solar, please follow the various steps set out in our User Manual https://www.tissotwatches.com/en-ch//e-usermanual/t-touch_connect_solar
Delete the T-Touch Connect app from your original phone, install it on the new one, and use your user ID and password to connect and recover your data.
The connection distance between watch and phone varies considerably depending on the environment you happen to be in. The average distance is between 10 and 20 metres.
You can delete your account at any time using the mobile app settings. Your personal data are deleted immediately. When you delete your account, the phone automatically disconnects from the watch.
Your watch’s pedometer counts steps according to your wrist movements. When you are driving, particular movements might be counted in the same way as when you are walking (just as with any other model of connected watch). The calculation of these “extra steps” is built into the margin of error tolerated by your activity tracker.
These data are obtained by means of algorithms that use the data provided in the user profile (height, weight, gender).
Check that the watch’s Bluetooth (T-Touch touch zone) and the phone’s Bluetooth are both activated. If they are, check that the Time 1 time zone is “Phone” (the hands display the Time 1 time).
If you are not receiving notifications on your watch, check the following points:
Check your watch is properly connected to your phone (Bluetooth icon displayed on the watch).
Activate the “Notification” option in the watch settings.
Check in your phone settings that the app has the necessary permissions to send notifications.
If your watch’s screen is black, this means the watch is switched off or in "Auto Sleep" mode.
- If your watch is switched off :
Press the crown for about 5 seconds to turn it on
Press the 3 push-pieces simultaneously for 3 seconds
If this happens when the watch is connected to your phone, you need to re-initiate the watch-pairing procedure.
- If your watch is in "Auto Sleep" mode:
Press one of the push-pieces in order to reactivate it.
The watch is only in English at the moment. French, Italian, German, Spanish and Chinese will be available on the beginning of 2021.
The watch’s battery life varies considerably depending on how the watch is used and its exposure to sunlight. In ideal conditions, the watch has a battery life of up to 6 months if connected and 10 years if used independently (without the app).
The connection between your watch and your phone is made via the Tissot app, thus enabling you to receive various notifications directly on your watch. It is perfectly possible to use your watch without connecting it to your phone, but these functions will not be available.
Like any high-precision instrument, a watch needs to be serviced regularly to ensure optimum functioning. The servicing frequency depends on the model, the climate and the care you take of it. As a general rule, we recommend that you have a service carried out every 4 to 5 years by a Tissot-certified service centre.
Check that your watch is placed on the charger correctly (back of watch flat against the charger). When your watch is on the charger, a charging symbol appears on the watch. If you have checked all this and your watch is still not charging, please return it to us free of charge using our prepaid dispatch service.
If your app has stopped responding, you need to use the settings on your phone force the app to shut down. Then restart the app.
The T-Touch Connect Solar is equipped with Bluetooth and requires the use of a smartphone that runs on Android 6.0 or above (available from 25/09/2020), or iOS 12.0 or above (available from 07/09/2020).
In your phone’s app store, search for the Tissot T-Connect app and install it. If it is not possible to perform this procedure, please contact our Customer Service department.
Check that Bluetooth is active on both your watch and your phone. If data on the watch and on the app are different, it may be that synchronisation has not occurred. Synchronisation occurs automatically every 15 minutes.
When you are disconnected for more than 2 hours, the watch turns Bluetooth off in order to reduce energy consumption. This means your watch will automatically reconnect when you are near your phone.
Check the status of Bluetooth in T-Touch menu -> Quick Settings -> Bluetooth and activate it if necessary.
Some phones running on the Android operating system do not allow apps to launch tasks in the background (including the one that allows reconnection) without the user’s intervention.
Here is the procedure for activating this option:
Go to the Settings menu and select Apps -> Permissions -> Autostart.
The battery-saving options may also prevent reconnection because they restrict background running and Bluetooth scanning:
Go to the Settings menu and select Apps -> Manage apps -> Select the App -> Battery saver -> No restrictions.
If this does not suffice, you can also set different permissions in the “Other permissions” menu in the app’s settings (just above the Battery-Saving menu) to ensure the app can run in the background and when the phone is locked.
In addition, if the date and time on your phone were set manually and are different from the date and time in the country you are currently in, this may prevent reconnection between phone and watch.
Provided the watch is within range of the phone, it is not supposed to disconnect. However, when the watch is disconnected for more than 2 hours it turns off Bluetooth, which must then be reactivated manually.
The hands show the time set in Time 1. Lock the watch onto Time 1 if you want the time on the screen to be the same as on the hands.
You can also synchronise the hands in the watch’s Sensors & Motors menu, by selecting: T-Touch/Settings/Sens.&Motors/Motors/Calibrate the hands
In case the T-Touch Connect Application is not open or do not work on the background or was fully closed, the function “Find my watch” will not work. Furthermore the IPhone will broadcast the alert at the current audio level of the phone. If the phone settings are turned down or off, you may not hear the alert.
The Function “Settle” is used to update the current timers of the watch directly from the phone.
Currently, the timer do not create any confirmation message of launch, you can nonetheless confirm that the timer as begun via the hourglass logo that appears at the top left of the watch screen.
