Here is an example of a 15J Swiss Fabrique d’Horlogerie Fontainemelon (FHF) “Ankergang” (anchor escapement) pocket watch from the early 1900s (possibly late 1800s). This piece is unbranded, signed only as a “Spiral Breguet and 15 Stene”, along with a boxed 0.800 silver purity stamp (80% pure silver as per Swiss authorities), Swiss mountain cock/capercaillie/grouse (not a pheasant) and an empty (no letter inside) Star of David maker’s mark. The inner dust cover is signed with a matching serial number and CUIVRE, indicating that it is made from brass. The right facing “bird” hallmark is also found on the inside of the case rim and on the pendant.

Having some difficulty in finding information on the Star of David maker’s mark.
