6152, 6154 and 6152/1 caseback classification

by on Sep.09, 2010, under General

The references produced in the 1950’s and 1960’s show clearly differences in caseback markings. Beside the different shapes of center cases and lugs between 6152, 6154 and 6152/1, different Rolex markings are visible when caseback removed.

The illustration shows the following caseback versions:
Ref. 6152 Rolex (with case number)
Ref. 6154 Montres Rolex S.A. (with case number)
Ref. 6152/1 Montres Rolex S.A. (without case number)

You can read and see more about the different versions of Ref. 615X watches in our book “The References”.
