A typical military watch, this Timor, with lots of lume so you can read the time in the dark. The hour hand has lost its luminous compound, though, so that needs to be replaced, and the movement needs a service.

Daniel sent it in for an overhaul.

We both first think that the hour hand lume has fallen off and lodged itself at the bottom of the dial, but that is not the case. This slightly unusual luminous compound application marks the bottom of the dial at night.

The military engravings on the case back.

The Peseux 190 movement with 15 jewels.

The bottom plate with the calibre mark and a little minute dial section that allows you to test the movement without putting a dial on.

The gear train – a very standard movement.

A new mainspring for the barrel.

The movement is back together and lubricated, and it’s time for adjusting. The hairspring stud position in the cock is fixed, so the beat error can only be adjusted on the collet.

Good amplitude, but the beat error is too high.

I carefully hold the balance between my fingers, covered by a sheet of watch paper, and slightly turn the collet. In order to determine how far and in which direction to turn, I have let down the power, and observed the resting position of the balance, and the resting position of the pallet fork. I then turn the balance from its resting position until the pallet fork is completely straight, and that tells me how far and in which direction to turn.

I’m happy with that. Very nice performance for a movement this age!

David Bill and Sons has re-applied luminous compound to the dial and the hands.

Back in its case, and with a new crystal, looking very nice again!
