Anyone have similar problem with DJ?

I have a 1999 16200, and although it keeps perfect time when wound, and is good for 2 days or so, the auto wind does not work either while wearing, or in a winder.
It's due for service anyway, since I purchased from original owner, who stated its been 10 or more years since service.
Just wondering if this occurs often, or it's indicative of other issues.
Thanks

It's not unusual for the auto-wind gears (reverser module) to stick or dry out. Sometimes the rotor can become disconnected from the winding gear too, or a broken jewel bushing can keep the axle from turning.

In the early days some watchmakers would just take out the auto-wind rotor if it had problems, and turn the watch into a manual wind version. I guess they figured that those new-fangled self-winding watches were just a fad that would go away.

Thanks for the reply. I'm sure it will be sorted during the service.
I appreciate the explanation!
