Here is something unusual – a Salvos Star pocket watch. 0 jewels. Yes, zero. Not one. And it ticks!
Salvos watches were made in Jura, Switzerland. The plate is just a bit of sheet brass, and so are the bridges. Let’s take it apart and have a peek, as this is quite interesting. The watch has a pin pallet escapement.
With the back removed, you can see the balance and wheel bridges
The hands come off …
The dial is held in place by a small screw below 6 o’clock. First peek into the movement – that’ll make your eyes water!
I said no jewels …
Bridges removed. I still have the movement in the case as I haven’t discovered yet how to remove the crown and I don’t want to break anything. At this point, I have already removed the screw that holds the crown / winding shaft in place and could have removed it
Still no reason not to give this watch some respect – only due to its age – so everything goes into the cleaning solution
Here you can admire the pin pallets in all their beauty
Balance and balance bridge – marvel the fact that somebody actually balanced it – see the little boreholes …
Start of the assembly – I’m using Moebius D-5 everywhere, apart from the balance pivots, which get Moebius 9020.
View of the balance and escapement – the screw on top of the balance shaft can be used to adjust the balance end shake.
Top plate assembled – note that the balance bridge also holds the pallet shaft. If you look at the hairspring, you can see that it has a “knot” in it. I take it out, removed it, and alas, we have a good amplitude!
As the screw that holds the winding shaft into place is under the dial, you have to put the movement into the case before putting the dial on.
And everything is back in place.
Surprisingly enough, the watch doesn’t perform too badly. Properly adjusted, it keeps time to within a minute a day – better than I would have expected. Oddly enough, there are no markings whatsoever anywhere – I would have at least expected “Adjusted to 5 positions” somewhere 😉
