The “Cortebert” symbol

by on Jul.20, 2010, under General

Interesting detail of the Rolex Cal. 618 / Type 4 and Type 3 movements: the small Cortebert symbol, engraved on the movement base under the balance cock. Both types of Rolex movements were used in Ref. 6152/1 watches (Type 3 = 15 Rubis version, Type 4 = 17 Rubis version).

The illustration left shows a Rolex Cal. 618 / Type 4 where the position of the “Cort” engraving can be found.

You can read and see more about the different versions of Rolex Cal. 618 movements in Panerai watches in our 2nd book “Vintage Panerai – The References”.
