I think we need a stickie for "dumb question of the day" because this probably belongs in there. TL;DR at the bottom. I've just called in at the local AD because they had a discounted DSOM in the window. It didn't do it for me and neither did the PO Chrono ... or the GSOM. I really wanted to like them all and, with three Omegas missing from my box for servicing, I have a hole to fill .... seriously, I will have no good looking tool watches for more than a month. Anyway, what I did like was the strap on the DSOM and with the deployant from the GSOM it'd be a great colour match for my older speedy. Simples. Right? Wrong. The A-D has no problem ordering both for me. I have to pay up front, not a problem again. I cannot return them (why would I want to?) Because, the girl in the store said she wasn't sure if the strap would fit between the case and the spring bar holes on the lugs .... and ... they wouldn't be able to find out ... nor would they take the strap off the one they had and check against my Speedmaster. So, has anyone put a new DSOM strap onto an older Speedmaster? Does it fit? TL;DR - do the straps for the DSOM/GSOM fit an older Speedmaster case (20mm lugs, not 19)?
