Ref. 3646: “Rolex inside”

by on Dec.29, 2013, under Allgemein

Close view on the movement of a Ref. 3646 / Type D. Used in Ref. 3646 watches from Type A to Type G, the Rolex Cal. 618 movement comes without Incabloc shock protection. Typical for the non-incabloc version is the serif font for the letters A-R (French) and F-S (English) engraved on the regulation device (later versions show “+/-” symbols – see also a comparing between Type 1 and Type 4 movements).

You can find more information about Rolex movements used in Vintage Panerai watches in our books “History1” and “History2”.
