Thomas sent in this watch, and told me it just stopped working…
Yep, that movement stopped working alright 😉 The rust damage is quite extensive, and will stretch to the keyless works as well. The water probably came in through the crown.
The case back has some rust on it, but as it’s stainless steel, that will just have come off the movement.
The dial has been restored.
As expected, the keyless works are affected as well.
The wheels will need some cleaning as well.
The gear train and pallet fork aren’t affected, so that’s good news.
The plate itself isn’t damaged.
On top of the rust damage, the mainspring is broken. My guess is that after the movement stopped through the rust damage, somebody desperately tried to get the watch going again.
A new mainspring. All the rusted parts have soaked in acid for 2 days, and I have then cleaned them with a brush.
Now that does look a lot better!
I have a bit of a beat error, so I have to take the balance out again to adjust that.
I’m happy with that.
With the acid, all rust is removed, and only a black substance is left, that can be removed with a sturdy brush.
The keyless works came up nicely after the clean-up as well.
The movement is cased. Compare the case screws with the first photo…
The stainless steel case back looks as good as new again as well.
Very nice indeed!
