Maintaining an automatic watch: the steps that make it last

An automatic watch is a small, living machine: hundreds of parts working day and night. Properly maintained, it can be passed down from one generation to the next. Here are a few simple steps that make a difference.

1. Wear it, or keep it moving

An automatic watch is wound by the movement of your wrist. If it remains still for several days, it will stop: nothing serious, but you will need to restart it and reset everything. If you wear several watches, a watch winder keeps them running and on time between wearings.

2. Set the date at the right time

On most date watches, avoid changing the date when the hands are between approximately 9 p.m. and 3 a.m.: this is when the date-changing mechanism is engaged. First, set the hands to 6 o'clock, then set the date, and finally set the time.

3. Respect its water resistance

• Make sure the crown is pushed in or screwed down, if applicable, before any contact with water.
• Never operate the crown or pushers underwater.
• After swimming in the sea, rinse the watch with fresh water if it is designed for this.
• Have its water resistance checked regularly: seals age.

4. Keep magnets away

Speakers, magnetic phone cases, bag clasps: a magnetic field can disrupt the hairspring and cause the watch to gain several minutes a day. If your watch suddenly starts running fast, a watchmaker can quickly demagnetize it.

5. Store it safely

Scratches mostly occur when watches touch each other in a drawer or tray. A watch box gives each piece its own cushion, protected from dust and direct light.

6. Plan for a service

The oils in the movement deteriorate over time. Depending on the brand, a full service is generally recommended every 5 to 10 years. A watch that runs significantly faster or slower than usual should be taken to a watchmaker.
