Calibre 533.3 Specifications (5247 Chronograph)
I'm curious if anyone could provide me with a few additional details on this movement, which appears to be the official successor to the Lemania 2320. From cursory research (Google), I know that the 533.3 beats at 6 hz rather than 5 hz and the movement is fitted with two extra jewels. There are also a few cosmetic differences between the new calibre and its predecessor.
Is there a reference or resource available if I wanted more information on the changes that have been made to the movement?
