Apparently this watch is well beyond repair, and I want to use the parts, whats the best way of disassembling a pocket watch? Any special tools I need? Here is the time piece in question:





I also picked up the inner workings of a 1920s ladies wrist watch, its studded with rubies and tiny coloured stars. It seems to still work, when I knocked one of the cogs it started ticking again, but whether the hands are still connected I don't know.

That pocket watch is an old Swiss pin-set from the late 1800's..  Tools you will need are jeweller's screwdrivers, and fine tweezers.
The most common sizes for the screwdrivers are   0.50, .60, .80, 1.0, 1.2, 1.4, 1.6, 2.0 and 2.5 millimeters, and I'd suggest a #2 style for the tweezers.

Hard to diagnose without having the movement in hand.  Does the balance still swing if you blow gently on it, or give the watch a shake? With these older Swiss unjewelled movements the two main problems you find are worn pivot holes, and broken balance staffs. The pin set works are pretty simple, and usuallly pretty rugged. Another issue is parts, as an example, it will be hard to find hands that have the correct hole sizes, you;d need to measure the pinion and then see what's available. Sometimes you get lucky and the hand holes are a common size, otehr times you need to take a set of hands that has a smaller size, and broach them carefully, until they fit.

I'll do my best, I'm not very good with my new fangled icongraph machine though....

Nothing really moves when I shake it, but it looks like a cog is loose on the inside....

Most likely, then you have a broken pinion (gear shaft) on that gear (or wheel, as they are called in watches). I'd say that its probably not repairable. In theory a good watchmaker could make the needed pinion, and re-fit it, but the cost would be pretty high, (as in several hundred dollars worth of time and labour)

Little update, so far the little ruby studded one is keeping very good time, I think it just needs a case!

I saw something similar once but it was a ladies rolex. about the same time period to. i could track down a ladies rolex that would most likely fit the movement

Many odd shaped movements go into other odd shaped cases (or even normal shaped cases) with the use of plastic spacers and a long setting stem. I wouldn't discount it just because of its shape.

If you can pass on the dimensions (length and width) in MM, I'll be able to wrok out the size in lignes, and see what it needs in terms of a case. Then, the hunt will begin..

As you are going to take the pocket watch apart, could you fit the ladies watch movement in the pocket watch case and then add another instrument in the space, eg a tiny compass? Would allow you to make a very individual face!

The pocket watch has no glass on the front, so it would be useless as a case Sad
