Geneva Seal 18 Jewel 7 Adj. Thin Pocket Watch Movement BC Wenger BWC (L57). Please see photographs for condition and size - the pictures form an important part of the description.Possibly a Frederique Piguet ebauche movement, very similar ones are used by Patek, Vacheron, Audemars etc. The dial is thin and currently loose, attached by two tiny screws on the front and don't want to risk damaging this attempting to place it back on. Superb piece for the collector. To receive updates about new listings, special offers and upcoming stock. We get new stock all the time and list several times a week!
