    Anyone with any ideas on who these marks are by? One is pretty visible. There is an M over the Swiss Made. The other is under the balance. It looks like a 3 inside a diamond.

    I haven't ID'd the caliber yet, but I have several of these movements. I popped off the dials and some are marked with an 'SFG in an oval' trademark which may identify them as made by Schild Freres Grenchen. This mark is different than their usual 'SF over G in a shield' trademark though. -Cort
