Introducing another piece of the puzzle – and one more surfaced in the United Kingdom: a Ref. 3646 / Type D with black painted brass dial and rare “Kampfschwimmer” engraving with initials of the first owner on its outer caseback. After more than 70 years the watch changed ownership once again and recently found a good new home at a Panerai collector from Germany, who provided the photo shown on the left.

The watch has been added into our database in March 2016 and comes with flat bezel (a typical feature of the watches with flat dials), onion shaped “Brevet +” crown (Type 11) and Rolex Cal. 618 / Type 1 movement. The watch has never been polished and has still its original plexi, showing the typical traces of aging. The inner caseback is signed with the Rolex SA hallmark, reference and case number. A similar 3646 / Type D watch with flat bezel and black painted brass dial will be auctioned in Glasgow on September 23rd, 2016 at Great Western Auctions.

A Ref. 3646 / Type D watch with black painted brass dial is featured in our book “History1” in chapter III together with the history of its first owner, a German “Kampfschwimmer” who provided us very interesting information about his service, training and how some of these Panerai watches “changed ownership” during the time when he was a POW (prisoner of war) in the summer of 1945 (page 206-207).

Watches of the Reference 3646 / Type D are also featured in our new book “The References” 1930’s-1940’s in chapter II.IV (page 398-531) including a historic photo of a German “Kampfschwimmer” wearing a 3646 with brass dial on page 475.

The Great Western Auctions Ltd. (GWA) in Glasgow / United Kingdom is selling a Ref. 3646 / Type D with anonymous, black painted brass dial in their upcoming Fine Art & Antiques auction (Lot 237) on friday, September 23rd, 2016.

The 3646 / Type D is recorded in our database since August 2016. The watch features a typical Rolex 618 / Type 1 movement, flat bezel and an onion shaped “Brevet +” crown (Type 11), original leather strap and large, nickel-plated brass pin buckle. The outer caseback of the watch has no personal engravings of the first owner. The inner caseback (with full polish decoration) bears the typical Rolex SA hallmark, reference and case number known for 3646 / Type D watches.

Watches of the Reference 3646 / Type D are featured in our new “The References” 1930’s-1940’s in chapter II.IV (page 398-531) including a historic photo of a German “Kampfschwimmer” wearing a 3646 with brass dial on page 475. Similar nickel-plated brass pin buckles of the WW2 era are featured in chapter V Straps and Buckles (page 677-685).

A similar watch 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 that this watch will find a good new home and remains surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]

…no, thats not the way we would describe the illustration of a SLC (which still represents a piece of the heritage on some of the latest Panerai watches e.g. PAM00425 or PAM00577, ). Even during its development in the “early days” before the Second World War, it was nicknamed “maiale” (pig) from those who were testing it at Porto Santo Stefano, La Spezia and Bocca di Serchio from October 1935 to August 1936.

Looking back into the history of the legendary “Human Torpedo” (as it was often named), one of the inventors of the SLC (Siluro a lenta Corsa / slow running torpedo), Elios Toschi, once described the two-man torpedo as “a mini, electrically powered submersible with a completely new design, whose crew (pilot and copilot) ride the torpedo in a sitting position and will thus be able to target enemy ports at night in cover of darkness using luminescent instruments to navigate. On their way to their targets, they are in a position when underwater to be able to cut through net barricades, remove obstacles and operate with great endurance at depths of up to 30 metres thanks to their breathing equipment…”

Read about the featured watches from Guido Panerai & Figlio in the first and second volume here.

Since we added a Ref. 3646 / Type E “California Dial” into our database in March 2016, the personalized caseback of this watch got our attention, too.

After the watch was auctioned earlier this year in May at Phillips (The Geneva Watch Auction THREE, lot 122, read the note in our watch point here), we continued research on the known personal dates, scratched with a sharp tool onto the caseback of the watch: Name, date of birth and home town of Heinrich Hauenstein.

Having already a few watches with personalized casebacks recorded in our database, we wanted to find proof about the personalized dates in general and if further information about the history of the first owner of this watch could be found more than 70 years after its use.

Since we exchanged information about Heinrich Hauenstein with his family, we know that he has passed away in 1976 at the age of 55. He was married but had no children. In 1951 he was a founding member of a shooting club in his hometown Solnhofen (Bavaria/Germany).

The family has recently shared a historical photo of Heinrich Hauenstein with us, dated October 1942 on the backside, showing him as a sailor of the German Kriegsmarine / Navy. To put a face behind the name on the caseback, we are pleased to publish here the photo from 1942 aside the auction catalogue from Phillips.

A long overdue meeting finally became reality: The invitation to visit one of the last WW2 “Kampfschwimmer” frogmen just had to be returned… one day! What better occasion for that one day than a personal shake hands on this veteran’s 93rd birthday? It was without a doubt an unforgettable meeting. Surrounded by his family and friends we finally met in person. Sitting together on his table, having a traditional Bavarian “Brotzeit” was more than a good time. Thanks for your hospitality, Jochen – stay in such a good shape!

Since 2010 we have been connected with veteran Jochen Burnus to publish the history behind a Ref. 3646 / Type D “Kampfschwimmer” in our book “History2”. Many personal documents and memories were provided by him for our research which helped us to capture not only the history of his friend Sigi, a member of the “Einsatzgruppe Keller” but also his personal history as a German frogman who ended up in American captivity in April 1945 after his mission against a pontoon bridge of the 83rd Thunderbolt Division at the river Elbe.

By his extraordinary good memories Jochen Burnus was able to give us a very detailed report on what happened before, during and after his mission, from training in northern Italy to the combat zones during the last months of the Second World War.

One part of chapter V is dedicated to his work as a recovery diver in Hamburg in the late 1940’s and bomb squad in the numerous waterways of Berlin in the 1950’s, followed by his career as professional diver across Europe until the end of the 1960’s. Accompanied with more than 60 historical photos and maps from various sources, the 112 pages of chapter V became the starting chapter of “History2” with a total of 480 pages. More information on chapter V can be found also here.

Our “History” books can be ordered only in our bookstore.

Enjoy reading stories behind these watches!

More than one hundred watches of the Reference 6152/1 are registered in our database today. Since 2009 the number of registered 6152/1 watches has more than doubled – seven years ago, 49 recorded watches were featured in our first edition book “The References” (sold out). Within the entire serial number sequence of the Reference 6152/1, we differentiate between watches with Rolex movements and the much rarer variations with Angelus movements.

How do we explain four different versions in our new book “The References” 1950’s-1960’s? Watches of the Reference 6152/1 are presented in four chapters, in order of the movement, the type of winding crown used and sorted chronological by their casing reference number, as follows:

Chapter VIII.I = Reference 6152/1
with Rolex movement and 8 mm Rolex crown
(featuring four different watches on page 878-921).

Chapter VIII.II = Reference 6152/1
with Rolex movement and Panerai crown-protecting device
(featuring ten different watches on page 922-1057).

Chapter X.III = Modified Reference 6152/1
with Angelus movement and 8 mm Rolex crown
(featuring three different watches on page 1212-1259).

Chapter X.IV = Modified Reference 6152/1
with Angelus movement and Panerai crown-protecting device
(featuring four different watches on page 1260-1313).

Each of the four chapters shows the different movement and dial versions recorded in our database with charts as can be seen on the coffee table shot of page 874-875, illustrating the relationship between registered watches with 8 mm Rolex crown and Panerai crown-protecting device of the Reference 6152/1.

Additional information on different hands, caseback engravings for different forces which used the watches as well as historical background on two 6152/1 watches first owners can be found, too. The overview of the four different chapters about Reference 6152/1 watches can be found in the first volume of “The References” 1930’s-1940’s on page 25-26 and 30-31 (chronological classification / reference quickfinder).

The new “The References” books can be ordered only in our bookstore. Enjoy reading!

One of the unique technical features of the GPF 2/56 compared to other watches from Guido Panerai & Figlio is the rubber sealing ring of the winding crown.

The famous patent 545668 from November 1955 can be seen right next to its realization on page 1148-1149 in chapter IX.II, showing the side of a GPF 2/56 “Luminor Panerai” with removed crown-protecting device and crown with its rubber sealing ring, making this area of the watch watertight when the lever is closed by axial pressure to the case.

Vintage Panerai watches with the legendary crown-protecting device are featured in the second volume of our book “The References” 1950’s-1960’s in chapters VIII (Ref. 6152/1 with Rolex movements), IX (GPF 2/56) and X.IV (Modified Reference 6152/1 with Angelus movements).

We would like to express our sincere words of thanks to Officine Panerai for making the famous patent 545668 available for the effective comparing view on the double page in our book, shown above. [Ralf Ehlers & Volker Wiegmann]

Bonhams London will auction a Ref. 3646 / Type D with brass dial in their upcoming Fine Watches and Wristwatches sale on June, 22nd (Lot 76). The flat bezel, as well as the Rolex 618 / Type 1 movement in combination with the (full decorated) inner caseback, bearing the Rolex SA hallmark with reference and case number, are typical features of Ref. 3646 / Type D watches.

The watch is recorded in our database since October 2015. It is mentioned several times in our book “The References” 1930’s-1940’s in the chronological classification on page 17, as well as in chapter II (page 44), chapter II.IV (page 401, 471) and chapter II.V (535-537), being the Ref. 3646 / Type D with the highest case number recorded in our database until today.

Noteworthy, this watch is another specimen found in the United Kingdom, where some watches were brought to as souvenirs from the Second World War by allied servicemen. After more than 70 years they re-emerge in different conditions, such as the watch up for auction at Bonhams.

A similar Ref. 3646 / Type D watch with painted brass dial is featured in our book “History1” in chapter III together with the history of its first owner, a German “Kampfschwimmer” who provided us very interesting information about his service, training and how some of these Panerai watches “changed ownership” during the time when he was a POW (prisoner of war) in the summer of 1945 (page 206-207).

We hope that this Ref. 3646 / Type D with brass dial will find a good new home and remains surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]
