I bought this from a well know internet auction site for £36 in May - every so often I have to buy my wife a watch so I can buy a few for myself! It wasn't running but was complete and didn't need any parts to get it going. I've cleaned, oiled (& demagnetized!) the movement and lightly polished the case and crystal.
Clearly the crown is not original, and I will need to find something more appropriate. I'm pretty certain the crystal is also not original as it is curved inside and out, whereas the rebate in the case is flat. Any offers of help on those items might be welcome :-)
The case is 14K white gold, and has been inexpertly repaired at some point resulting in some of the inlay melting slightly although this is not really obvious unless you look closely. It will need an 11mm strap which I'm sure will be a doddle to find (I've found a black one but my wife said a green one would be nice!)
The 5AP movement (based on an Aurore-Villeret 9) has 15 jewels and an overcoiled hairspring with a bimetallic balance. The train bridge is a single piece, although cut to look like seperate bridges for each jewel. The movement cover retains its original acetate sheet.
There are two patent dates inside the case back - but no patent numbers, so I don't know what these refer to.
There are a couple of similar watches in the database in the "Miss America" group from 1928, although these have integral lugs and don't have the mitre effect in the case corners.
