I have the prior revision of 45mm B, there was some discussion about this model having handset from 42mm version and inner hour index also out of proportion. As far as the 2012 version vs 2011, the following might be true:
i) inner hour index larger diameter
ii) 1200 triangle lowered & slightly larger
iii) all number fonts are larger
iV) hand set maximum width of each hand is slightly larger, including sweep seconds, also wider
....am i right with any of this?
(apologies if this was discussed already. )
