SSTEEL Posted March 30, 2017 Report Share Posted March 30, 2017 I've search, and have previously ordered many gen crowns and tubes for Omega models in general, mostly the older models, but now I'm trying to find the part numbers for the Genuine Omega crown and tube for this watch.. DSC08329 by Micky Aldridge, on Flickr Its a GMT Planet Ocean 45.5mm Can anyone help, specifically part numbers from cousins would be ideal.?

SSTEEL Posted March 30, 2017 Author Report Share Posted March 30, 2017 Ive narrowed down my search to these two crowns. 9 x Ø6.60mm Screwdown SS (7.60mm) Cousins ID 42274ST 9 x Ø7.60mm Screwdown SS (7.45mm) 42277ST The GMT model I need the crown and tube for is listed as a 43mm model on Omega site.

SSTEEL Posted April 11, 2017 Author Report Share Posted April 11, 2017 Bumping this, as I am stuck on which tube I need now. Link to comment Share on other sites More sharing options...
P4GTR Posted April 11, 2017 Report Share Posted April 11, 2017 (edited) What size is the rep crown, does it match one of those? That tube looks like it will probably make a gen tube swap extra "fun" as usual on the Omegas... The Omega model number system is a nightmare. I always laugh when reading Omega forums and such, "hey check out my new 234223./13/235.23..2/23/2/5.52". Just imagine them saying that at a watch get together, must sound like a calculus club. Any other naming convention would be better. Its like trying to learn another language- Gibberish. Edited April 11, 2017 by P4GTR Link to comment Share on other sites More sharing options...
SSTEEL Posted April 12, 2017 Author Report Share Posted April 12, 2017 I'll measure the rep crown later and post the measurements here mate. Link to comment Share on other sites More sharing options...
SSTEEL Posted April 22, 2017 Author Report Share Posted April 22, 2017 Rep crown is 6.59mm in diameter, depth of 3.60mm So I guess the correct crown would be the 42274ST The tube is all I need now. Link to comment Share on other sites More sharing options...
