Omega Seamaster 120m 2311.21 (midsize) - Crown replacement

Greeting everyone,

I’m struggling to identify the part number for the gold crown on my 36mm quartz Omega Seamaster, reference 2311.21. Could you assist me in finding the correct watch part number so I can search for it? Do you think this is a component that’s readily available, or is it restricted to Omega service centers and authorized repair facilities?

I initially thought crown 069BA42132 might be compatible, but I’ve since learned it’s designed for the automatic Omega Seamaster 120M, reference 2301.21.00. I’d appreciate any guidance to point me in the right direction. Thank you!

@Archer you're the best!

@ArcherI want to confirm that the correct number is 069BA42132, not 069BA42123, since both are similar part #s. Could you please verify this?
