Maintain your watch: To tell the time, a watch, like any complex mechanism, requires a minimum of maintenance.

Cleaning the watch

To maintain the shine of your waterproof watch and its metal bracelet (if equipped), we recommend that you use a soft brush soaked in lukewarm soapy water and brush it gently. After this operation, as after a swim in the sea, rinse your watch carefully with fresh water.
For "non-waterproof" watches, clean your watch with a soft, dry cloth. A leather strap should not be washed.

Winding your manual mechanical watch (mechanical)

Winding is done by turning the crown clockwise. Winding is complete when the crown is blocked. It is advisable to wind it regularly, once a day. Do not attempt to wind a mechanical watch beyond the locking point as this may cause the mainspring to break.

Winding your automatic mechanical watch

A watch equipped with an automatic mechanical movement winds itself as your wrist moves. Unworn, your watch has a power reserve of approximately 40 hours.

If you have not worn it for more than 40 hours, wind it manually using the crown to guarantee its necessary power reserve.

It is important that the watch fits well on the wrist. A strap that is too loose equals a loss of battery life (the watch loses the ability to wind itself automatically).

Changing a quartz watch battery

It is recommended to change your batteries every 18 months, unless it has a longer lifespan provided by the manufacturer, which can sometimes reach 11 years. Some major brand quartz watches with central seconds hand are equipped with the end of battery life (EOL) indicator system. Approximately two weeks before the end of the battery's life, the central seconds hand jumps every four seconds to signal that the battery is about to stop. When this signal appears, it is recommended to have the battery changed within 4 to 5 weeks to prevent the battery from leaking and damaging the movement. Indeed, when the battery is worn out, it risks losing a corrosive substance which can damage it forever.

Date change

Do not change the calendar to quick fix (or quick date) between 10 p.m. and 2 a.m. This is the moment when the gears are replaced for automatic date change. There is a risk of damage.

Overhauling a mechanical watch

Service your mechanical watch every two years. Mechanical watches have a multitude of moving parts (more than 90), covered with synthetic oils. It is recommended to carry out a regular overhaul of this mechanism in order to limit wear and maintain good precision. This operation is called "redressing".

Watch waterproofing

It is recommended to check the water resistance of a watch at least every 3 to 5 years, or even every year if it is often used underwater.

The waterproofing of a watch protects the movement from dust, humidity and any risk of deterioration in the event of immersion. The gaskets that ensure watertightness can wear out due to the different temperature changes to which the watch is exposed. Each time the battery is changed or the watch is serviced and each time the box is opened, for whatever reason, it is important that the watch undergoes a water resistance test.

It is important not to pull out the crown to change the date or time in water. When the crown is pulled, water may enter the box. For watches with a screw-down crown, check that the crown is screwed in perfectly before going into the water. For chronograph watches, do not trigger the chronograph underwater, as water can seep through the pushers.

If condensation forms in your watch, you should quickly go to a watchmaker who can remedy this problem. If you can't, the best thing in the meantime is to put the watch on a warm object and pull the crown out to drain some of the water, but this will not replace the intervention of a watchmaker.

After bathing in the sea or in chlorinated water (swimming pool), it is recommended to rinse your watch in fresh water. Non-waterproof watches should not be exposed to steam, immersed in water or any other liquid. The water resistance of a watch should never be considered definitive. Whether it is dust, water or pressurized water (diving) and especially in the latter case, the materials which provide this function are susceptible to wear, deterioration through aging or impact ( glass).

  • Self-winding or quartz watches remain water-resistant much longer than manual-winding watches because there is almost no wear on the winder.
  • Seals deteriorate more easily when exposed to sudden or significant temperature changes such as showering, prolonged exposure to the sun followed by immersion in cold water.
  • Before placing the watch in contact with a humid environment or immersion, ensure that the sealing parts are in place (winder not in the time setting position, crown and pushers screwed on the diving watch).
  • Certain water-resistance functions being ensured by different technical products or complementary parts, violent shocks, even if they leave no visible trace, can damage the functioning of the watch but also its water-resistance.
  • In the event of humidity in the watch (fogging) or significant water intake, it is necessary to consult a watch specialist who will ensure a new waterproofing for your watch or overhaul and waterproofing if the mechanism requires it.
  • It is recommended to wear a bracelet adapted to the watch (width and length) and the type of use. Opt for metal, rot-proof or special quality leather straps for diving watches.

Water resistance test according to standard NF S81515 (Second category watches, waterproof from 4 bars to 60 bars)

B.1 Condensation test

It allows you to check beforehand the absence of humidity inside the watches.

The pieces are placed on a heating pad having a temperature of 40°C to 45°C for 30 minutes. we then place on each glass a piece of felt of 1 cm 2 previously soaked in cold water (10°C to 15°C). The felt is held for approximately 1 minute, then quickly removed and the glass wiped with a dry cloth.

If condensation appears inside the surface of the watch glass, it is then eliminated.

Note: The felt can be replaced with a drop of water.

B.2 Air pressure test

Each watch is placed in a waterproof enclosure and subjected to an air pressure of 4 bars.

The air flow entering the watch and resulting from the variation of the air volume of the enclosure as a function of time is measured using a pressure gauge. It should not exceed 30 micrograms/minute.

B.3 Depression test

The watches which are wound and set to the time are suspended in a waterproof tank half filled with water or oil, at the discretion of the depositor and immersed completely in the liquid. Then, a depression of 0.5 bar is gradually applied and maintained for 1 minute.

Any prolonged emission of bubbles is localized (glass, caseback, crown, etc.) and will result in the watch being discarded.

The watches are then raised above the liquid and the pressure returned to its normal level.

B.4 Water pressure test

The watches which have successfully passed the previous tests are suspended in the waterproof tank half-filled with water and submerged. The pressure is gradually increased to the control pressure and maintained at this level for 5 minutes. As before, watches that no longer keep time or are flooded. are eliminated.

B.5 Condensation counter-test

This test is carried out according to the process indicated for the condensation test (paragraph B.1) described above. Watches which show traces of condensation after 30 seconds of rest are considered non-waterproof and refused.

The different categories of watches regarding water resistance

  • Non-waterproof watches for which no guarantee of watertightness can be given. Most of the time, these are old pocket watches (onion, rooster, fob, etc.) or bracelet with a very basic casing or a particularity such as openings called "windows".
  • Sealing against dust (Dust Proof), which is the worst enemy of the mechanism, because it quickly harms its proper functioning, is a protection for common watches. A waterproof watch is necessarily dustproof but not vice versa.
  • Third category waterproof watches (Water resistant). From 20 to 30 meters or 2 to 3 bars. These watches intended for traditional use are reserved for hand washing and other household work, etc. They support contact with a humid environment and surface immersion.
  • Second category waterproof watches (40 to 60 meters or 4 to 6 bars). For swimming only.
  • First category waterproof watches (60 to 100 meters or 6 to 10 bars). These are theoretically well-designed sports watches supporting deep immersion.
  • Then there are from 100 to 11,100 meters for sports and diving watches.
