Omega Geneve with Seamaster bottom cover

Hi everybody,

I was able to acquire a very beautiful 1968 Genève. Glass and crown have unfortunately already been exchanged, but the history of the watch is complete and I still have all the papers and it comes from the first owner 😀

Now the question arises of the reference number of the watch in order to be able to replace the glass and crown with Omega parts.

The lid is a Seamaster lid with the Ref 136.011 which is also mentioned as ID on the purchase receipt from 1968 and the receipt for the 1969 work exchange. There are also other numbers written in the cover that I can't do anything with. (yellow note).
The reference number belongs to a Seamster 600.

According to my research, when the Genève and Seamaster generation at that time was phased out, the cover of the Seamaster was also used for the Genève. Can someone confirm that or at least contribute to it 😀

I have now noticed several Genève with Seamaster but I have not yet been able to find a final explanation for them. Maybe now.

Thanks in advance.

Best regards
Maximilian

136.011 was indeed a ref that came in multiple model variants - they can have Genève, Seamaster 600 or Seamaster written on the dial.

I’ve seen a few of the 136.011 Genèves with Seamaster case backs so I do think you’re alright with this one, “136.011” is your correct reference number. No idea what the numbers on the yellow paper might stand for, though.
