I found this gem on eBay a couple of months ago, ADU35 in total (inc shipping). I'm really quite surprised by the quality and low cost of ladies watches (I must be the only person shopping for them..). This particular Elgin has a 10k GP case and works perfectly (after cleaning):
.. I'm still trying to track down what Elgin movement this is, so if you know the caliber number feel free to post it in the comments section.
This may be the smallest movement I've worked on, the next photo will show the relative size of the watch to my club-like thumb, with the stamped 10k case back:
Once the watch is opened up, the low cost is even more surprising. The movement has 15 jewels and is adjusted to 4 positions. All the jewels are set in nickel?? chatons, which suggest that this movement is designed for a long life.
The tear down:
The click, anchor and screws are all black-polished and the click spring and yoke spring are blued - something which cannot be seen with my low quality camera - again, very surprising for a cheap watch (which is now obviously seen as under priced).
Overall, a superbly designed and finished movement.
