Depending on the type of watch you wear on your wrist (mechanical, electronic, quartz, water-resistant or not), there are a number of things you need to know before making it your everyday jewel. A watch requires more or less meticulous maintenance, depending on the type of mechanism.

When you buy a watch, you may be wondering about the basic settings (changing the time and date on your watch) and the level of water resistance.

Basic settings

To adjust your watch, remove it from your wrist for easier handling. Be careful when handling the crown, which gives access to the various settings.

Time change

All watches are generally constructed in the same way: the first notch on the crown is used to change the date, and the second notch to change the time. Always turn the hands clockwise.

Date change

When changing the date, avoid doing so between 8pm and 4am. Doing so could disrupt the mechanism, or even break a tooth on the date disc (the number of the day of the month). In fact, the date-change process starts a few hours before and after 00:00.

Essential gestures

When you have finished setting, push the crown back against the case as far as it will go. If your watch has a screw-down crown, make sure you have tightened the screw. These two gestures are essential to preserve the water-resistance of your watch.

If in doubt, our jeweler-watchmakers will be happy to help you.

Sealing

What is waterproofing?

Your watch, whatever it is, is made up of mechanical and electronic parts that are sensitive to water and humidity. Depending on the model you choose, the degree of water-resistance will vary. So it's important to determine how you intend to use your watch before you buy, in order to choose the level of water-resistance that best suits your daily activities. Water resistance is measured in ATM (atmosphere), BAR (water pressure) or meters.

The different sealing levels :

Non-waterproof watches: non-waterproof watches should not come into contact with even the slightest amount of water. Do not wear your non-waterproof watch in the shower, and avoid rain or splashing water.

Water-resistant to 3 ATM / 3 BAR / 30 meters: A watch that's water-resistant to 30 meters doesn't need to be submerged, and can only withstand occasional splashes and rain. Nevertheless, we strongly advise you to remove your watch from your wrist when washing your hands, doing the dishes or taking a bath or shower.

Water-resistant to 5 ATM / 5 BAR/ 50 meters: A watch water-resistant to 50 meters will withstand gentle contact with water (your wrist frozen in a bath), but will not withstand movements and direct jets that risk letting liquid in via the glass or push-buttons.

Water-resistant to 10 ATM / 10 BAR / 100 meters: This powerful waterproofing will enable you to come into contact with any source of water, even while swimming!

Water-resistant to 20 ATM / 20 BAR / 200 meters: Designed for advanced sports use, water-resistant to 200 meters can be used for deep-sea diving, jet-skiing and other diving sessions. However, be sure to have the water-resistance of your watch checked regularly.

What should I do if my watch has taken on water?

To avoid this inconvenience, always make sure that the crown is fully inserted, and have your watch repaired promptly if you discover that the glass is cracked.

If your watch still comes into contact with water and fogs up, forget the hairdryer and simply place the object in a warm, dry place to allow the condensation to evaporate.

You can open the crown and place your watch on the dial to allow faster evacuation, but don't risk opening your watch yourself. If fogging persists after 48 hours, it's urgent to take your watch to a professional.
