Tried to catch a nice view of the engraved caseback of the 6152/1 “Luminor Panerai”…

Features of the watch:
Reference: 6152/1
Dial: “Luminor Panerai” (sandwich, engraved)
Case number: 124537
Movement: Rolex Cal. 618 / Type 4

Pretty nice weather conditions during the easter weekend in Germany… I just had to take out the “Arillo Luminor” Ref. 6152/1 and tried to catch nice lights and shadows on the dial…

Happy Easter!

Since January 1st, 2010 we have received more than 40 new entries in our database, spread over all references. Most of the new entries are in the reference 6152/1.

Very interesting for our research is a “group” of three Ref. 6152/1 watches in a row: 124805, 124806 and 124807.

The first two watches have both “Luminor Panerai” dials. Watch 124805 has a crown protecting device signed “10”, while its “brother watch” 124806 has the crown protecting device signed “9”. It will be interesting to compare these two watches with close lower numbers to see if they have crown protecting devices signed with matching numbers (between “1” and “8”) to them.

All three watches come with the –  typical for this reference – Rolex Cal. 618 / Type 4 movement (17 Rubis + Incabloc shock protection) which is one of the main features of Ref. 6152/1 watches with Rolex movements.

Both watches with “Luminor Panerai” dials have the “double pencil” hands, but they are not 100% identical: watch 124806 has the “sharp pin” versions, watch 124805 has the “dull pin” versions. Both watches, 124805 and 124806, have no matriculation number engraved on the caseback.

Watch 124807 comes with a “Marina Militare” dial and so it could be part of a different order, in case that the Italian Navy ordered watches with identical dial inscriptions from Panerai. This question can be answered in the future when we have found more watches which have close case numbers to these three here. 

Watch 124807 has the crown protecting device signed “7” and the “BREV. ITAL.” trademark inscriptions. The caseback of this watch bears a matriculation number: “M.M. 005”. It holds also the “double pencil” hands with “sharp pins”.

Nice detail view of a Rolex Cal. 618 / Type 4 movement, working accurate in a 6152/1 “Luminor Panerai” watch.

The characteristic features of the Type 4 movement are:
17 Rubis, Incabloc shock protection
(balance cock engraved with a “plus-minus scale”)
16 Lines, power reserve approx. 36 hours.
18.000 half-oscillations per hour.

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”.

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.

Movement view of two Ref. 6152/1 watches: Rolex Cal. 618 / Type 4 movement (17 Rubis and Incabloc shock protection) and the Angelus Cal. 240 SF (15 Rubis and Incabloc shock protection, signed “JUIN .61”) on the right.

Both watches have the legendary crown protecting device. The device of the watch with Rolex movement (124806) is signed “BREV. ITAL” and “9”, while the watch with Angelus movement (124784) is signed only with “3”.

Interesting to see, that the watch with Rolex movement has different hands (double pencil shape) compared to the watch with Angelus movement, which usually comes with single pencil shaped hands. Note also, that the size of the “Luminor Panerai” is different (smaller on dials with Angelus movement).

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)

Left watch: Ref. 3646 / Type D
Rolex Calibre 618 Cortebert Type 1.
