I have a Rolex Cellini, but don't know too much about it, and can't find any technical information on it. I want to know things like, is this a hand winding watch, does it have auto winding function? After one winding, how long can it last. I have attach a picture for reference.
I want to know the following information
1. 型號
2. 機心
3. 上鍊方式
4. 年份
5. 上鍊一次可用多久
6. 何處可以找到它的資訊
