To avoid any misunderstandings, I'd like to add some information! It's a working item!! As I mentioned in the comments, I was asked about maintenance, so I'll clarify. It's a hand-wound watch that's running well, so a watchmaker should be able to overhaul it. This is a hand-wound ROLEX Precision watch with diamonds. While there is some wear and tear, it's in very good condition. The mechanism has also been confirmed to be working. - Brand: ROLEX - Model: Precision Thank you for looking.
