Rolex inside…

Movement view of two vintage Panerai watches: Rolex inside…!
The differences in decoration and engraving of the bridges are clearly visible on Rolex Cal. 618 Type 1 and Type 4 movements.
During our research work we created for a better understanding a subdivision of 4 movement types, which is an important feature of our database of today’s existing vintage Panerai watches. Basically they are all Cal. 618, but they show differences in many details.
Beside the engravings and different decoration, the main identifying features are:
Type 1 = 17 Rubis, no Incabloc (used in Ref. 3646 Type A – G and in Ref. 6154)
Type 2 = 15 Rubis, no Incabloc (used in Ref. 6152)
Type 3 = 15 Rubis, Incabloc shock protection (used in Ref. 6152/1)
Type 4 = 17 Rubis, Incabloc shock protection (used in Ref. 6152/1)
