Movement Serial No.:
Case Serial No.:
Looks like a 1951 His Excellency "XX" to me. It's housed in what appears to be the original clam shell case with booklet as found in an estate; according to the watchmaker I purchased it from. Gold plated back and movement marked "L1". Keeps perfect time.
I find it quite odd that there are currently 9 HE XX examples in the database; one is a 1948 and the other 8 are 1949. Thought I would add a 1951 for good measure.
