Here I come to save the day--maybe!
Putting a Yuki 7206 onto my 1601-based Space-Dweller was as close to a perfect fit as I could imagine. Gen bracelets are a different story--especially Oysters, since I don't think they were an OEM option for the 1601. x58s should be the best fit, but these will likely be a bit loose around the lugs. Rep 455Bs won't help you, since they're way too big...
If you like rivets, I'd go with the Yuki option. Alternatively, a Jubilee with x55s should be perfect. I think this is what ubi did on his build.
Superb dial, by the way. That didn't come from Italy, did it?
