I can recall not being able to find replacement straps for my 1016, back in the '60's, because 18mm was the widest commonly produced strap width...
I have a drawer full of vintage Elgin's, Hamiltons, Bulovas, Walthams, etc., that I haven't worn in a few years, since I discovered 44-47Mm Pannys...They just look ridiculously puny...Even my (rep) no CG "Bond" sub feels tiny...
Hopefully, some day, the style trends will shift back to smaller stuff, and I can feel comfortable with my ancient treasures again!!
