Restoration of a rare vintage Omega Seamaster Cosmic 2000 - Omega 1012 Service

This time i´am restoring this beautiful Omega Seamaster Cosmic 2000.
It´s powered by the Omega 1012 automatic movement and it beats at 28800bph, the lift angle of the balance is at 52°. Omega introduced this model back in 1972 on the international collection.

This Omega-Watch has one of the rare press-in cases. The inner case (container) is press-fitted into the outer case (jaquette) by an additional O-Ring.
This O-Ring seems to have completely dissolved on this watch. The container doesn´t hold in the jaquette anymore and the residue of the O-Ring sticks everywhere. Apart from that, there are some signs of wear on the case-parts, the crystal has many scratches and the crown comes lose as soon as i tried to set the time.
The movement works but loses more than 1 minute per day.

I need to disassemble the whole movement, clean all the parts and re-assemble it with some fresh oil. The setting-lever is a bit bent, thats the reason why the crown comes lose when i tried to set the time. I fixed the setting-lever and after reassembling everything, this watch is in a fantastic beat (+2 seconds per day) again.

I hope you liked this restoration, if so, like, comment and subscribe ;)
