I own the above-noted chronometer. Unfortunately, the staff pivot broke and it is obviously inoperative. I may end up getting it serviced professionally, as I messed up a staff last year trying it with basic watch tools, and I'm trying to figure out if there's anything special about it, thereby enhancing the value. This would help my bullet-biting when it comes to shelling out a lot of money for a service and repair. Any help is appreciated. Cheers.
