Jason from Germany sent in two watches, and the first one I’m servicing is his Glashuette. It’s post-reunification, so it has an ETA movement, and not a GUB. Not a bad thing 😉
If you look closely, you can see that the inside of the crystal is hazy. An odd thing to happen with a pretty watertight diver’s watch, and you wonder if that was caused by overheating (oil fumes) or fumes coming off the dial paint or lume.
A lot of dirt on the pendant tube thread, but that’s usual.
The hazy coat on the inside of the crystal comes off easily.
And I start off with the bottom plate.
A quick look at the timegrapher – a bit of a beat error, a very low amplitude, and the movement is too slow. Definitely time for a service!
A look at the keyless works.
The auto winder assembly.
The parts of the keyless works.
Now it’s time for the top plate. Balance removed, and the gear train is next.
The old mainspring is a bit tired.
Everything goes into the cleaning machine.
The new mainspring.
As usual, I start off with the balance jewels, which I oil and assemble under the microscope.
The gear train is back in place and oiled.
The balance goes in, and the movement starts ticking.
Now that looks a lot better! These ETA 2824s are great performers, very reliable, very accurate, and I like them a lot.
The bottom plate goes back in.
Dial and hands are on, and I’m ready for casing.
I case the movement without the auto winder.
Then I oil and put together the auto winder.
And everything is complete with a new gasket.
Having put everything back together, I notice that the hacking second feature doesn’t work. And, looking back at the photos, I notice that the stop lever never was there… Not a problem, I’ve got the missing lever in stock.
The missing lever is put in place, and I can put the movement back together.
A simple, and beautiful watch.
