What is the ring in the Omega watch?

There's an autopilot in it. When you wear it, your arm will swing and the autopilot will swing with it.

So you can wind the watch.

This is the so-called self-winding movement.

There is some friction noise when the autopilot swings.

If you don't shake it, there will only be a ticking sound when you leave.

There will be the friction sound of the autopilot when the hand is turned.

This is normal.

If there is abnormal noise, such as "crash", it may be that the parts have fallen off.

If it is a quartz watch, there is something wrong.

The above two cases were sent for repair.
