Omega Geneve Automatic Calibre 565 166.041
The Calibre 565 is one of Omega’s most respected movements — automatic, smooth-winding, and exceptionally robust.
This Genève represents everything collectors love about the golden era of Swiss watchmaking.
applied hour markers, original hands, and date window at 3 o’clock deliver classic Omega balance, while the automatic Cal. 565 movement — widely regarded as one of Omega’s finest workhorses — provides reliability and precision.

Stripped down the Omega watch, found dial had been glued to calendar plate, one of the dial feet was stuck in the mainplate and the other has the retaining screw missing.
The watch was clean but no sign of lube, lower balance jewel retaining spring loose.
Ordered a new mainspring and dial feet.

Mainspring: GR2533
Dial Feet: 0.69mm
Click spring: Omega 450-1105
Jewell Retaining spring: Inca 175.03

Pallet fork: 565-1316
Lower spring broke when i tried refitting it after cleaning, looks like someone has had trouble in the past as both sides of the jewel holder are marked.
Also when i came to re-assemble the movement, the upper pallet fork pivot snapped off!!
I found a used pallet on ebay for £48 so i bought it, it has now been fitted and the watch is back to servicable condition and running at -2/+10 s/d
This one tried my patience a little, even considered selling it for parts but i am glad i didn't now it is running.
