Silke, thank you for the ebay link! I just need to get it measured, as it is in tenth of a milimeters, and going to order it!
Guys, please suggest what cleaning I should ask for by watchmaker for the first one? I am totaly inexpierienced in this. I just read, that polishing is bad for the watch as it removes some metal from the surface.
