These have pretty long lugs, like a Hamilton does, so buyer beware that it may fit larger than the case width might seem. A better measurement, which is clearly diagrammed at Bertucci's website, is the lug-to-lug measurement.
Also, I have the A-1S (in white) and I adore it. I wear it as my beater, and it is tremendous.
I'll pass on this one because 40mm is a bit large for my dainty wrists, but to anyone wondering, Bertucci punches way above its price tag...
DanTreviewNo way this watch is 40mm, in my view this is very misleading & has been falsely advertised by DROP. Its 36mm at best, I purchased 5 of them as gifts, the only good thing is the Nato strap & the MSRP they suggested was incorrect as youbcan buy them all day long for $55 - DX3 Model.
