What is the part number for the Omega leather strap and the deployant that came with the previous Speedy 1861 (ref. 311.33.42.30.01.001)? And did it come in different lengths? Thanks
I purchased that Speedmaster configuration in 2016. The strap Part No. is 98000008 The clasp Part No. is 94521613 I am not certain whether the strap was available in different lengths. I'm inclined to think no.
Check out https://www.genteel-handmade.com/ for more options and colors than Omega. I got this one for my 1861 awhile back and am very pleased with it.
There's a few sites to search around, but this one seems the right mix of reputable and somewhat reasonable pricing: https://www.watchobsession.co.uk/collections/omega-watch-straps That's if you want/need OEM Omega. Genteel I've heard are good, as well as Aaron Bespoke/Combat Straps.
16mm O94521613 18mm O94521813 Not sure about the straps, but check Genteel Handmade, and just get one custom made.
