Apologies if this has been discussed before, but the Marine Chrono is quite unique by virtue of its central minute chrono counter. It's nice from a functional POV (though I'm not convinced I like it over the 5237 say) and I was wondering if it uses the Lemania 5100 movement (or derivative) famed
for this central minute counter?
I know the Lemania 5100 has quite a cult following built up around it (especially since it's been discontinued), but it is really a very economically minded piece of engineering with a large array of plastic components and not at all something Breguet would ever use as a base for one of their watches.
The movement is instead based on the Lemania 1372 found in the Breguet Type XX and Type XXI. There's been a huge amount of virtual ink spilled by yours truly on the subject of this movement (the Cal. 582 anyway, the one in the Marine Chrono is slightly different) so I won't bother rehashing it here (try the search engine if interested), but suffice to say that it is somewhat of a workhorse by luxury watch brand standards, but several large steps up from the Lemani 5100.
Kano - yep and I see that my more recent posting here re 5237 crown has been met with an equally resounding success : zero!
_john - many thanks for the info. That answers all my questions, puts my mind at rest and indeed explains the sweep seconds at '9' and the small date at '6' (as per XX).
