so is there a triangle shaped metal part inside. That on is mounted with a axle at the center and turn around inside like a rotor on a automatic movement. Then you read the markers inside the tool when you adjust, one marker is one second. So the oil help so the "rotor" will be stable when you adjust.

Oh wow!

Not many dare to get into a Rolex, but that's what you have to do as they are easy to work with and difficult to break. Logical solutions that can be understood. I probably wouldn't have get into a Patek, I also have limits, even if it doesn't seem like i...

As I usually say to the Danes, the only thing that is better in Denmark than in Sweden is the view over the strait. πŸ˜‚
