Omega Seamaster 2598.80.80

[Cmmb8519]

Hi all

It is more than 8 years that I water pressured test my Omega Seamaster Professional 300m and, as expected, it has a couple of leaks on the Helium valve and in one of the pushers, apart from the case tube that is very wore and needs replacement. I serviced the movement one year ago and all seems to be fine with it, but the case needs a good overall to all components.

Omega Model: 2598.08.08

Inside the case back there are four codes (I'm assuming the first one is the case number??):

- 178.0504 / 378.0504 / 175.0504 / 375.0504

I need the:

- Mini gaskets for the crown (both inside the case tube and inside the crown), the two pushers and the helium valve

- Back case gasket

- Case tube

 

Challenge for an amateur is, where do I get all the case parts??

Is there technical documentation from the case that I can check all Omega part codes for these?

Is it possible to get the original part codes? or better look for generic parts? or assortments?

Thanks in advance for any insight on what / where to look for!

Have you searched for parts and info on Omega forum and some of the others.

By chance just yesterday I happened to see that cousinsuk.com seem to have a lot of parts for Omega. Perhaps worth a look?
