For an automatic watch
An automatic watch is wound naturally by the movements of the wrist.
If you're not wearing it for several days, it's a good idea to wind it manually by turning the crown a few times.
For a mechanical watch
A mechanical watch has to be wound every day with the crown and has a power reserve of 36 to 48 hours.
For a quartz watch
The quartz movement is the most accurate and durable movement. It requires no daily intervention and operates with a battery that we recommend changing every two years.
