37mm "gap"
I've (so far) captured and organized data - everything from size to case, dial and hand details and calibre details like BPH, jewels, etc - on 660 distinct references from Breguet and Blancpain - Classique, Marine, Heritage, Tradition, Leman, Villeret. It's not complete and probably has bit errors here and there but it's interesting (to me, at least)
One thing the data for these two makers illustrates is a 37mm "gap" that I think actually represents a market opportunity. You can see here larger numbers of 36mm and 38mm references, with very few 37mm ones.
As I add to the data, I will be interested to see whether other makers fill in that gap - and if so, I will be definitely interested in what they have to offer!
