Maintaining your watch : To tell time, a watch, like any complex machinery, requires a minimum of maintenance.

Water resistance


Water resistance test according to standard NF S.81515


Different categories of waterproof watches


Cleaning the watch


To keep your waterproof watch and metal bracelet (if equipped) shining, we recommend using a soft brush soaked in warm soapy water and brushing gently. After this operation, like after a swim, 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 a 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 blocking point as this can cause a rupture of the mainspring.


Winding an automatic mechanical watch


A watch equipped with an automatic winding mechanical movement is wound as you move your wrist. When not worn, your watch has a power reserve of approximately 40 hours.


If you haven't worn it for more than 40 hours, manually wind it using the crown to ensure its necessary power reserve.


It is important that the watch fits well on the wrist. A loose bracelet is equivalent to a loss of autonomy (the watch loses the ability to wind itself automatically).


Replacing a quartz watch battery


It is recommended to change the battery every 18 months, unless it has a longer lifespan planned by the manufacturer, which can sometimes reach 11 years. Some quartz watches with a central second hand from major brands are equipped with the end-of-life battery indication system (EOL). About two weeks before the end of the battery life, the central second hand jumps every four seconds to indicate that the battery is going to stop. When this signal appears, it is recommended to have the battery changed within 4 to 5 weeks to avoid the battery leaking and damaging the movement. Indeed, when the battery is used up, it may lose a corrosive substance that can deteriorate it forever.


Date change


Do not change the calendar in quick correction (or fast date) between 10 p.m. and 2 a.m. This is the time when the gears are reset for automatic date change. There is a risk of damage.


Revision of a mechanical watch


Service your mechanical watch every two years. Mechanical watches have a multitude of moving parts (more than 90), covered in synthetic oils. It is recommended to perform regular maintenance of this mechanism to limit wear and maintain good accuracy. This operation is called a "re-dressing."


Water resistance of the watch


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


Water resistance of a watch preserves the movement from dust, moisture, and any risk of deterioration in case of immersion. The seals that ensure water resistance can wear out due to the different temperature changes to which the watch is exposed. Whenever the battery is changed or the watch is serviced and every time the case is opened, for any reason, it is important that the watch...
