Functioning of the watch
- What are the precision tolerances of our mechanical watches?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.
- What are the precision tolerances of our quartz watches?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.
- How much is the power reserve of our self-winding mechanical watches and how do they work?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.
- What is the difference between a chronograph and a chronometer?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).
- Can Tissot watches be worn in the water?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.
- What precautions should be taken to guarantee optimum functioning of your Tissot?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.
- What is the difference between a self-winding and a manual-winding movement?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.
- What is the difference between Lépine and Savonnette pocket watches?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.
- What is an Autoquartz watch?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.
- What is a tachymeter and how is it used?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.
- What is a unidirectional bezel and how can it be used for deep-sea diving?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.
- What is the Flyback function?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 IVTwo 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.
- What is the difference between a partial service and a complete service?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 Tissot certified watchmaker can determine why the watch has stopped as well as identify the appropriate maintenance.
- Where can I have my watch serviced?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.
- How often does a watch need to be serviced?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.
- Can my watch be serviced and do you have the spare parts?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.
- How much does it cost to service my watch?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.
- What is the battery life? What does EOL mean?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.
- What does the sales warranty cover?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.
- What does the service warranty cover?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.
- Can I order spare parts directly from Tissot?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.
- What should I do to ensure that my watch continues to provide excellent service for many years?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).
- Can I wear a Tissot stainless steel watch if I am allergic to nickel?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.
- What does PVD mean?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.
- What is titanium?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.
- Do the dial and hands of my watch contain radium or tritium?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.
- How can I know whether my Tissot watch contains tritium?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.
- What should I do if the hands and the LCD display no longer indicate the same time?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.
- Is it possible to erase the data recorded in the Sea-Touch log book?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.
- How many dives can be recorded in the Sea-Touch log book?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.
- The Sea-Touch depth meter is graduated up to 59m. Why not more?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.
- What does the spanner icon mean in the LCD display?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.
- What is the level of precision of the Sea-Touch depth meter?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.
- My Sea-Touch will not set to Dive mode. What should I do?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.
- When will my credit card be charged?If you pay by credit or debit card it will be charged as soon as we have verified your order. Upon verification of your PayPal information your order will be processed and your account or credit card will be charged.
- I want to visit a store to look at Tissot watches. How can I find a store near me?Please visit our store locator page.
