Rolex Cal. 618 Type 2 classification
by Volker on Nov.29, 2010, under General
Small – but interesting – differences can be found in the Rolex Cal. 618 / Type 2 movements used in vintage Ref. 6152 Panerai watches: the bridges received different engravings, being technically the same (15 Rubis, no incabloc shock protection). Note the different position of ROLEX and 15 RUBIS!
For a better understanding, the differences are colored:
Rolex Cal. 618 / Type 2 = pink
Rolex Cal. 618 / Type 2 mod. = yellow.
Such differences in engraving the bridges are similar to the Rolex Cal. 618 / Type 1 and Type 1 mod. movements, which were used in Ref. 3646 Panerai watches. We have published these differences in our 2nd book “Vintage Panerai – The References”, in the chronological classification (page 12-29), and also illustrated in chapter I.VII (page 149).
