General Information About Automatic Watches

Automatic watches operate using a self-winding mechanism that uses wrist movements to power the movement. If an automatic watch is not worn for an extended period, it will stop and need to be manually wound.

First-Time Use of an Automatic Watch:

• Before wearing the watch for the first time, it must be manually wound by turning the crown about 20 times.

• Automatic watches must be worn regularly to maintain power reserve.

• If left unworn for several days, the watch must be manually wound before being used again.
