This Tissot Seastar also belongs to Michael. He bought it and it was DOA. Only one thing for it …

There is a fair amount of dirt in here, and that's good enough of a reason for the watch not to work.

This is the calibre 2481, with the first incarnation of the quick-set date which requires pushing the crown in. The quick-set mechanism was modified in subsequent versions, and doesn't work that well on the 2481.

There is dirt throughout, and it's probably been some time since this movement has seen a service.

No rust or obvious damage. I've removed the balance jewels, and work my way through the bottom plate.

After all the parts have gone through the watch cleaner, I reassemble the movement again.

Top plate done, and the balance is swinging.

Only half wound, this is looking very good!

Starting on the bottom plate, I notice that a leaf of the cannon pinion is missing. Time to order a new one …

Now I can reassemble the bottom plate.

Bottom plate complete bar the hour wheel.

The movement goes back into the case.

The case back gets a new gasket.

With new case screws (the old ones were missing), I put in the auto-winder assembly and close the case.

Final check on the timegrapher – I'm happy with that!
