Wendy sent this lovely Omega over for a service. The dial only has 6 dots, and is chrome plated. No Omega symbol, nothing. Looks very classy!
This, on the other hand, doesn’t look classy. The movement is barely ticking and has a tiny amplitude.
This movement is pretty small – 13.5 x 17.5 mm, and 3.25mm thick. The serial number dates the watch to 1944-1947.
The movement has a bi-metallic screw balance, and the jewels are of course not shock protected.
Time for some cleaning.
The nicely decorated bottom plate.
The main spring is still of the old type, so the watch probably hasn’t been serviced for some time.
All goes into the cleaning machine.
The escape wheel top pivot is broken, but I’m very lucky, and there is a complete movement on eBay, which I order from the US.
And here is the replacement movement. I could have bought a new escape wheel for the same price as the used movement, but with the performance I’ve seen, it won’t hurt to have a complete movement on stand-by…
The new mainspring.
Putting the cap jewel and regulator on the balance cock.
Barrel, centre and third wheel are in.
And the barrel bridge is complete.
Then, the wheel bridge, pallet fork and balance go in, and the movement is ticking, albeit not very well. I change the balance over from the donor movement, and things look a lot better! Good thing I went for a complete donor movement.
The bottom plate back together.
And the dial back on. Some of the chrome plating is worn off, but considering the age of the watch, that’s no surprise, and doesn’t really hurt.
The hands are back on, and I can put the movement in the gold case back.
Very nice indeed! For a small movement that’s over 60 years old, this is very good.
