The watch isn’t working, and there is a good reason for it!
A little hint here – you can’t remove the case back 😉 Looks like various people have tried, and to no avail.
This is the only way in.
The dial isn’t screwed down properly, and just lifts out. Also, there is no hour wheel, and no pawl or pawl spring.
Quite a bit of dirt here.
Having a look at the minute wheel, I notice that half of its teeth are missing.
Normally, the watch would be beyond repair – just the parts to get this right would be more expensive than the value of the watch. But to the rescue comes a client of mine, Earl, who recently sent in a 784 to replace the date ring on his Tissot. He kindly donated the rest of the movement, and I’m passing his generous gesture on to Richard. Any parts movements I get given by clients are marked as donated, and I pass parts from those movements on for free – just to encourage others to show the same goodwill. Just got a donation of a Chinese fake movement today, and I’m sure I will be able to put that to good use one day!
Bottom plate almost cleared – just the setting mechanism and the balance jewel to go.
Reassembly starts with the balance jewels.
Top plate complete and ticking. Great looking movement, and clean again!
Now I adjust beat error and beat rate.
With the donor parts, the bottom plate comes back together.
… and we have a working bottom plate again.
Ready for the dial and hands.
Ready for the crystal.
Great looking watch – and ticking again!
