Time for an inspection!
The “USE KEY…” on the back is the hint how to get into this watch. The back is solid, so doesn’t open. The only way in is through the front.
With the glass removed and the winding stem taken out, the movement comes out of the case. No case screws, and the case ring rests in the case, so something is wrong here.
Inside the red circle is a case screw that has fallen into the hairspring.
There is the case screw, happily sitting on the pallet fork bridge.
Clean looking movement.
All is well on the bottom plate, too.
I start off by putting the balance jewels back together and oiling them.
Then it’s time for a new hairspring.
The hairspring got damaged by the screw, and that in both vertical and horizontal direction. As a new balance with hairspring is £20, I take the easy way out and order a new one, rather than sweating an hour over the old, bent one.
Nice looking movement in good condition.
And this is rather good looking, too!
The hands have seen rather a lot of bending and messing around with, but considering the state of the dial, they fit together.
I fit a proper new crystal (with a tension ring) as whoever serviced the watch last put in a normal acrylic crystal without tension ring.
The bracelet gets a proper clean – nice watch!
Roger asked me to upload a photo of his Tissot, and I can’t post photos to comments, to I’m putting it up here (see the discussion thread below).
