Dear friends,
I just realize that the 2 automatic movements with micro-rotor used, on the one hand, in the regulator, and on the other hand in the new travel time watch related this year at SIHH, share the same basic reference 31-260. However the look totally different ! And the "new" one seems to use much less silicon technology.
Do you know what are the differences and to which extent they are basically the same ?
Thanks
