The Revue Thommen looks very nice. All of these look very nice. With any of these watches, how does one determine whether it is chronometer qualified. The ads I've looked at for the Revue, Hamilton and others don't specify that. Can any 7750 or any other movement for that matter, be adjusted to that level. I would imagine that some have better parts than others, even within the same movement - I mean, some 7750's are better than others.You can do quite a bit of research here and on the net about your queries, but in short:
A whole new world is opening. This is exciting.
Theoretically any mechanical movement can be sent to COSC (the main certification body in Switzerland) by the manufacturer / watchmaker for certification. All that this means is that the particular movement passed stringent accuracy tests in various positions BEFORE INSTALLATION in a watch. The very next movement on the production line may be installed without being sent for testing, and may very well be just as accurate as the tested one. However, only individually tested movements may be certified as being a "chronometer".
Certain movements are known for their inherent accuracy, and the COSC rating makes little or no difference once it has been regulated.
A watch with COSC certification will normally cost quite a bit more than a non certified one. Buying a watch with such certification is no guarantee that it still is as accurate as the day it was tested!
I can write a lot on this topic, but just do some searches....
