How to operate a watch?

remontage montre de luxe

1) For a mechanical watch with manual winding, the driving force is governed by a spring connected to the crown. You have to turn the crown from bottom to top to arm your watch until it hangs. This way your watch will be charged to the maximum of its power reserve and will work until the energy stored by the spring runs out. It is possible to arm your watch at any time.

2) For an automatic watch, the operation is the same as for mechanical watches. When you roll up the crown of your watch, the spring arms and operates the mechanism. On the other hand, automatic watches are equipped with an oscillating weight that keeps the kinetic energy when you move your wrist.

3) For the quartz watch, a battery runs the movement for several years (at least one year for basic models). Note that when the battery is exhausted, on some models, the needle does not beat every second but every five seconds. It is the indicator that must alert you to the change of the battery.

Maintain my watch:

It is advise to bring your watch at your watchmaker approximately every five years. Do not forget that your watch is established by fine mechanics. As a car, it is necessary to make a revision, to wash it and to put new oil. So you will offer to your watch an optimal longevity.

How to clean my watch?

If your watch is mounted with a leather strap, you must disassemble it. A cloth with a little soapy water will wash your watch perfectly. Be careful, if it is an old watch, contact with water is strongly discouraged.
