Went to try-on today. I have ~165mm wrists and after trying on both 38 & 42 watches I ended up happy with the 38mm. Both looked just fine. The 42mm looked more like a sports watch and for this go round I wanted something that would work for more occasions so the 38mm really looked great (and not like a bulbous chiclet). But that's not my current problem. Tried the modern buckle in both medium and large. I fit the medium on the last hole and the large on the smallest hole for a snug fit. Argh!! So I'm concerned the medium won't work if I walk a long distance and my wrists swell. But if the band stretches at all, the large won't work either. The modern buckle leather is rather thin and might be prone to stretching (?). Anyone here have experience with (thin) leather bands and which way might be the best to go?
