Of the less than 70 registered watches of the Reference 6152/1 with Rolex movement and crown-protecting device, almost a third feature a “Marina Militare” dial. The specimen shown here was a new entry into our database in 2016, which is also engraved on the caseback with the “long version” marking Sommozzatori Marina Militare, together with a three-digit number (S.M.Z. M.M. XXX). Less than fourty casebacks with such a matriculation number are recorded in our database until today, used on both, Ref. 6152/1 watches with 8 mm Rolex crown and Ref. 6152/1 with the crown-protection device from Guido Panerai & Figlio, no matter which movement is inside (Rolex or Angelus).

This 6152/1 is powered by a Rolex 618 / Type 4 movement, which can be found in more than 80% of all Ref. 6152/1 watches, recorded in our database until today (Type 4 = 17 Rubis and Incabloc shock protection.

Find information about the different matriculation numbers on Ref. 6152/1 watches in our book “The References” 1950’s-1960’s in chapter VIII.I (page 913-917). Watches of the Reference 6152/1 with Rolex movement and crown-protecting device can be found in chapter VIII.II (page 922-1057).

Introducing another piece of the Vintage Panerai puzzle – and one more from the watches, which were used by the Carabinieri, bearing a rare engraving on its caseback. Until today we have recorded only seven Ref. 6152/1 in our database with C.C. engraving and matriculation number on their casebacks.

Beside this watch, four similar specimen with “Luminor Panerai” dial and crown-protecting device are part of our database. The new owner has recently provided photos and informations, after purchasing the watch from the family of a Carabinieri veteran, for our records.

More than 50% of all recorded Ref. 6152/1 watches with crown-protecting device bear a “Luminor Panerai” dial. Inside the watch works a Rolex Cal. 618 / Type 4 movement which is known in more than 80% of all Ref. 6152/1 watches, recorded in our database until today.

The evolution of Vintage Panerai watches from Guido Panerai & Figlio from the 1930’s to the 1960’s can be symbolized in a photo like the one shown here: from a cushion shaped case with soldered lugs and an onion shaped crown to a much stronger, massive case with solid lugs and the legendary crown-protecting device.

The early References 2533 (chapter I) and 3646 (chapter II) are explained and with rich reference to several variants by their number groups in the first volume “The References” 1930’s-1940’s. This overview is complimented by the legendary Mare Nostrum chronograph (chapter III), rare compasses (chapter IV) used in the Second World War and some of the few straps and buckles which rarely survived after more than 70 years (chapter V).

Spotted! The historic photo on the left shows two members of the Col. Moschin (Special Forces of the Italian Army / 9º Battaglione Paracadutisti d’Assalto “Col Moschin”). A depth gauge from Guido Panerai & Figlio can be clearly seen on the wrist of the right incursore, holding diving equipment in his left hand.

Compasses and depth gauges made by Guido Panerai & Figlio are featured in several versions (with “Radiomir” and “Luminor” luminous material) in chapter XI of the second volume of our book “The References”. Chapter XI.I is featuring compasses from Guido Panerai & Figlio. Five different models are featured from page 1320 to 1333. Three with “Radiomir”, two with “Luminor”. Chapter XI.II is featuring depth gauges from Guido Panerai & Figlio, similiar to the instrument which can be seen in the photo. Ten different models are featured from page 1334 to 1367. Six with “Radiomir”, aimed to 7, 30, 35 (2 versions: adjustable and non-adjustable dial), 50 and 60 meters. Four with “Luminor”, aimed to 7, 15, 16, 30 and 40 meters.  

Information on “The References” 1950’s-1960’s (second volume) can be found here.

Dr. Crott Auctioneers will have a Ref. 3646 / Type D “Kampfschwimmer” with painted brass dial and rare engraved caseback (bearing the initials of the first owner “KG”) in their upcoming 95th Auction on May, 6th 2017 (Lot 424).

The watch has been recorded into our database since 2004 when it was on display in a museum. After seeing it again for the second time in 2006, it surfaced now, eleven years later, for sale on auction to find a new home.

Noteworthy about this watch is the original leather strap (double keeper) and the coated brass buckle as well as the unpolished condition of the case with flat bezel and typical internal details (decorative polish on the inside of the caseback, Rolex SA hallmark with reference and individual case number, Rolex 618 / Type 1 movement) matching our database criteria for being a Ref. 3646 / Type D.

A tubular crown (signed “Oyster Patent” / Type 13) is screwed down on the neck of the 47 mm cushion shaped case. At this stage of our research, we are not able to link the engraved initials “KG” definitely to one of the frogmen veterans in our records.

Features of the watch:
Reference: 3646 / Type D
Dial: “Kampfschwimmer”  (painted brass, anonymous)
Case number: 260XXX
Movement: Rolex Cal. 618 / Type 1

Watches of the Reference 3646 / Type D are featured in our book “The References” 1930’s-1940’s in chapter II.IV (page 398-531) including a historic photo of a “Kampfschwimmer” wearing a 3646 with brass dial on page 475. Brass dialed Ref. 3646 / Type D are featured on page 468-493). In this part of the book, an overview of different decorative polish on the inside of the caseback (Type A – Type G) can be found on page 486. A Ref. 3646 / Type D with painted brass dial is featured in our book “History1” in chapter III together with information about the first owner, a German “Kampfschwimmer”.

We hope the watch will find a good new home and that it remain surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]

The photo on the left shows a Ref. 3646 / Type D (featured in chapter II.IV) placed on a historic photo of a cunning tower of a Royal Italian Navy submarine, on which an instrument (aiming device, described as “traguardo di puntamento per il lancio di siluri”) with luminous Radiomir display from Guido Panerai & Figlio can be seen on the left. The firm and close contact with the Royal Italian Navy, which existed many years prior to the start of producing watches, meant that a prerequisite had been established within Panerai: One only uses the best components.

The early References 2533 (chapter I) and 3646 (chapter II) are explained and with rich reference to several variants by their number groups. This overview is complimented by the legendary Mare Nostrum chronograph (chapter III), rare compasses (chapter IV) used in the Second World War and some of the few straps and buckles which rarely survived after more than 70 years (chapter V).

Why do some Ref. 3646 watches come only with a six digit case number embossed on their inner caseback? Where did the Rolex hallmark and reference number go? In which of the seven different number groups of the Reference 3646 is this the case?

Our book “The References” 1930’s-1940’s answers these questions in two chapters by measurement results and illustrated cross-sections (page 537-551, 638-639 and 644-645). The coffee table shot on the left shows a Ref. 3646 / Type G with a technical illustration on page 618-619 in chapter II.VII.

Chapter II.V = Reference 3646 / Type E
(featuring four different watches on page 532-573).

Chapter II.VII = Reference 3646 / Type G
(featuring two different watches on page 608-645).

In many respects, the GPF 2/56 set new standards in terms of design at Guido Panerai & Figlio: The casing diameter, now at a stately 60 mm (or 66 mm including the crown-protecting device), made the earlier Panerai watches with their 47 mm casings look small by comparison. This was also the first time a rotating bezel with five-minute increments was used, a luminous reference point at 12 o’clock and three other major indices at 15, 30 and 45 minutes. The inside of the rotating bezel is fixed securely to the casing and caseback with six screws at a distance of 60° on the underside. If the six screws are loosened, it is possible to lift off the caseback, the rotating bezel and the Plexiglas crystal from the watch casing. Unlike earlier Panerai watches, the caseback of the giant GPF 2/56 does not feature a thread but is fixed securely to the casing by the six screws. Compared to the Panerai watches used during the Second World War (bezel and caseback „twisted“ together by their internal thread onto the holding ring of the movement) as well as the watches produced in the 1950’s (bezel pressed onto the casing and caseback with external thread screwed onto the centre of the 47 mm casing).

While the crown-protecting device was a very prominent, almost “superimposed” addition to the Reference 6152/1, and could only be integrated into the Rolex casing to a certain degree as a result of its construction, the GPF 2/56 clearly shows the “completely seamless integration” of the legendary crown-protecting device.

The coffee table shot on the left shows page 1092 – 1093 in chapter IX.I of our book “The References” 1950’s-1960’s with a photo of the screwed caseback of a GPF 2/56 (left) and an illustration of the construction of the “kept together by six screws” GPF 2/56 (right). Enjoy reading!

With regard to the evolution of watches from Guido Panerai & Figlio, one particular weak point has been often mentioned that has been improved hugely over time: the strap loops soldered on to the pillow-shaped casing of the Reference 3646. With the Radiomir watch shown here, a Ref. 3646 / Type B with riveted plastic dial, we can take a closer look at precisely this weak point and show an example of a Reference 3646 that was not returned to its original condition after being damaged. The watch shown in the photo on left is described in detail on page 228-237 in chapter II.II of our book “The References” 1930’s-1940’s.

With the experience collected during the Second World War, the aim was primarily to increase the stability of the watches’ lugs. The soldered wire watch loops had been revealed as a weak spot and Guido Panerai & Figlio worked hard to improve them and the result was a success – in shape of the watches of the Reference 6152, 6154, 6152/1 and last but not least the huge GPF 2/56. The lugs of these watches were all created out of the casing itself and no longer soldered on (read also page 723-733 in chapter VI of our book “The References” 1950’s-1960’s) as it was the case with the watches of the Reference 3646.
