Rolex, Ref. 3525
This reference was one of the first “Oyster” chronograph and was available in stainless steel as well as 18K pink and yellow gold.
When this watch first appeared in the early 1940s it cost 350 Swiss francs in stainless steel; in 18K gold it cost 935 Swiss francs.
This particular example is part of the first series of references 3525, made circa 1937-1939 with the serial numbers on the case-back rather than between the lugs.
