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 2nd book “Vintage Panerai – The References”.
Even with an impressive case size of 47 millimeters, the Ref. 6154 watch looks pretty small compared to the instruments around, which have a case size of 70 x 90 mm.
