I was wondering if anyone can explain the different model swiss movements. Also, I am under the impression that there are many watches and watch brands that use the same exact swiss movements. (which is the most common?) If there are links for the internet for explainations or information on the different swiss movements, that would also be a bid help. I have quickly become very interested in this (and watches in general) but unfortunately I don't have the time to really do some quality research. Thanks in advance for all of your help.
