I really like this one with the diamond dial. It needs a new crystal that I am hoping to get in a lot I have coming soon. So I photographed it with and without the crystal to show the pretty dial.
The case is 10k yellow gold filled that is date stamped L1. The movement is a 6BC with 17 jewel that is also date stamped L1.
The 1955 price list has a Carol "A" and a Carol "C" at $71.50 but I have not been able to confirm which variant is for the yellow.
