Service: Omega Geneve 165.041 calibre 552

Dougie sent in his grandfather’s Omega Geneve. The crown isn’t original, and it needs a service and a new crystal.IMG_7221

The case back gasket has dissolved, and there is lots and lots of dirt.IMG_7223

The movement looks very good indeed – original, no scratches, all you want to see!IMG_7226

The bottom plate looks pristine, too.IMG_7228

The amplitude is very low, but that’s no wonder considering the watch hasn’t been serviced for decades.IMG_7233

No scratches, and just a bit of dirt.IMG_7244

Whilst the movement parts are in the cleaning machine, I turn my attention to the case and bracelet.IMG_7246

All ready for reassembly.IMG_7354

The new mainspring ready to go into the barrel.IMG_7358

The base movement is back together and beating.IMG_7364

Now that looks pretty good!IMG_7365

I case the movement, and put a new gasket into the case back.IMG_7366It’s extremely rare to see a vintage Omega in such good shape. Do I really have to send it back? ๐Ÿ˜‰

  1. I have seen this kind of gaskets especially on 70s Omega and Tissots, probably they made or ordered the gaskets togheter considering Tissot and Omega shared a lot of production back then (and probably also Lanco)… Maybe other manufacturers used them as well, but I haveยดnt seen them elsewhere.

  2. That has obviously been taken care of by a careful gentleman!
    Lovely example!
    I have seen many Omega gaskets dissolve like this. Specific for Omega, or just a general issue with old gaskets like that?

    • I’ve seen those in any brand of watch. Must have been the type of rubber they were using back then. Newer type gaskets just get hard, but don’t dissolve any more.
      You can easily clean up those old dissolved gaskets with methylated spirit.

      • Thanks! Have a cal613 Omega Gevenve with the same gunk remains…. Will try to clean it up as described.
        Are you using ISO/Swiss gaskets, or dedicated “Omega” branded ones when you replace them?

        • Most of the time, I use the original Omega ones. On my own watches, I measure the inside and outside diameter, and the thickness, and go with the standard ISO gaskets if there is one available in the right size.
          Omega certainly won’t make their own gaskets, so I doubt there is a quality difference. But my customers do of course want original Omega parts.
