Going with this 1957 Bulova “President” today....32.4mm case....39.5mm lug-to-lug....and a thin 8.5mm case back to the top of the crystal....just a nice clean design.
I've wanted one for a few months and this came at a deal I was very happy with and almost full 2 year service warranty from Bremont.
At 43mm it's slightly bigger than I'm used to but very impressed with it.
