Back bears the signature FIX. Clasp marked SAVARD and Jour? I can’t read the rest. Aged tarnish and patina on back Pin is silver tones and may be a replacement but it has an interesting hinge configuration that appears original. L so it is a conundrum. FIX was a French company created in 1829 by FRANCOIS AUGUSTE SAVARD, inventor of a very high quality gold plating process whose slogan was: “his armor is made of gold”.
