I’m practicing with this lovely old Services wristwatch. Disassembled, cleaned, rebuilt. It was jammed solid before with years of grime, now things move but it won’t work. Two things I need to ask:

1. Mainspring is set. Does this mean watch won’t hold any power or is it that I can’t get it to latch on the bridle?

2. I can get the balance to oscillate and the pallet fork to swing with it, but that doesn’t seem to make move the escapement. All the pivots appear to be located in their holes. What have I got wrong?

 

Thanks in advance.

I’ll get a new ms on Tuesday evening then when I meet with my sensei and see if that does anything. I’ll also get him to look at it, I think it may be pivot port wear as they are all steel. I’ll be back!

On most movements the barrel teeth are visible on the edge of the movement.

Shake the watch to set the balance moving and use a screwdriver to push the barrel along on the visible edge and see if the movement runs. What you are doing is simulating the power of the mainspring.

Pin-levers need more power than a jewelled lever movement.
