How oddly shaped? I'd try a Hirsch Mobile. It comes in 20mm, which should fit your Seamaster. I got mine shipped from England for $50 total each. Really, really nice for the price. I'd rate the quality as identical to the actual Omega rubber strap you see above on my watch, minus the foldover clasp.Christmas Present just arrived today registered mail. First luxury watch purchase. I live in Sicily and was able to get it through a military website for $750.00 off retail. Have a question, I have a oddly shaped wrist and would like a non-metal band. Any suggestions? Tell me what you think. Card me!
