eaxactly this. I picked up a minty (in appearance) Chronostop last year. The movement is pretty much dried up. Miraculously, it still keep time, for about 4 hrs, with a full wind. Service cost for it is 50% of the price of the watch. I bit the bullet and finally got it serviced. It’s awesome that you can service your own wrist blings. If you need to practice on a Rolex GMT, I’d like to volunteer mine
