A very elegant watch with a gold case back that holds the round movement – a Felsa 4122. Let’s open it up and have a look …
The dial has some slight damage around the edges, and the hands can do with a polish.
The Felsa 4122 movement and the gold case back.
The movement is 7 3/4”’ or 17.2mm, so quite small for a gent’s watch.
Tidy construction – here you can see the gear train, and the Felsa mark and calibre number.
The bottom plate.
The hunt for a new mainspring takes me quite some time, and poor Maurice is without his watch for the summer…
All parts ready for the cleaning machine.
I put back the pallet jewels – you can see the tiny circle of oil between the cap and balance jewel.
New mainspring in the barrel.
The wheel bridge back in place. A beautiful little movement.
About the same size as a 10p coin!
I polish the hands and put the dial and hands back onto the movement.
Now the case gets some attention. I start by cleaning it with a pegwood stick.
When the crystal was glued in the last time, a little bit too much glue was used. I press the crystal out so I can clean this up.
Now I remove the old glue.
That looks better! I’ve tried to remove the black markings from the dial, but they won’t come off without causing damage to the dial.
A set of new spring bars won’t hurt, either.
Great looking watch.
