We added another previously unknown watch into our database – yet another piece of the puzzle surfaced, which marks the first entry of a Ref. 3646 / Type D in 2022 and in total the Type D #107 in our records.

The “Kampfschwimmer” watch with anonymous sandwich dial appears with a rare engraving on its caseback, bearing the initials of the first owner and the name of the unit he belonged to (Marine Kampfschwimmer 1945).

The inner caseback of the watch (full polished, read more in “The References” 1930’s-1940’s on page 486-487) bears the Rolex SA hallmark, reference and case number known for 3646 / Type D watches. Inside the watch is a Rolex Cal. 618 / Type 1 movement with typical decorations and engravings on the bridges (ROLEX 17 RUBIS / FAB. SUISSE).

Still sewn onto the soldered lugs is the original leather strap (!) including the large and very rare nickel-plated brass pin buckle. The watch has its original onion shaped winding crown and the typical blued steel hands with original luminous material.

Features of the watch:
Reference: 3646 / Type D
Dial: “Kampfschwimmer” (sandwich, anonymous)
Case number: 2605XX
Movement: Rolex Cal. 618 / Type 1

The first owner of the watch took part in a frogmen mission against Russian pontoon bridges across the river Oder at Aurith, near Fürstenberg, in March 1945. You can read about these frogmen missions in our book “History1” in chapter II on page 83-123. The first owner was born in 1924 and passed away in 2000.

The watch is accompanied with an interesting documentation of his service during the Second World War and further information about his life, after he was released from British imprisonment in 1945.

The first watches for the pilots of the “new weapon” SLC were delivered in the middle of the 1930’s by Guido Panerai & Figlio to the Commando del 1° Gruppo Sommergibili of the Royal Italian Navy. According to the timeline of the development of the top secret slow running torpedos (siluro a lenta corsa, short: SLC) by the inventors Teseo Tesei and Elios Toschi, waterproof and luminous instruments for the pilots were necessary to carry out proper exercises and to control the SLC in depth and darkness.

The chapters I and II, dedicated to the first watches for underwater use (Ref. 2533 and 3646) take the readers of our book “The References” 1930’s-1940’s into these early years. Teseo Tesei and Elios Toschi’s ideas became real. But strategic decisions after the Italo-Ethiopian War stopped the secret SLC project. The tests with these small weapons were archived and the Royal Italian Navy focused their interest in huge battleships, cruisers and destroyers.

The SLC project was re-started by the 1st Flottiglia MAS in 1939 at the advent of the Second World War. With the first missions of the Mezzi d’Assalto carried out from August 1940 onwards, the demand for skilled operators as well as new equipment – and more instruments for the operators – grew fast. An early Ref. 3646 / Type A, dated to April 1940, is featured in chapter II.I followed by the timeline of the missions carried out by the operators of the Decima Flottiglia MAS, the special commandos of the Royal Italian Navy.

The photo shows page 96 of “The References” with a historic photo from June 1940: The two inventors of the SLC, Teseo Tesei and Elios Toschi, Alberto Franzini and Gino Birindelli above their co-pilots stand together with a royal visitor: Principe Aimone di Savoia Aosta, Duca di Spoleto –  just a few weeks before the first missions of the new weapon SLC were about to write naval history.

Read more about “The birth of a legend – the first Panerai watches (1935-1939)” in chapter I, followed by the timeline of the missions during the Second World War in chapter II.I – more information on the historic content in our “The References” book set with a total of 1392 pages can be found here. Read about the featured watches from Guido Panerai & Figlio in the first and second volume here.

A few days ago we received an interesting photo from the grandson of a German “Kampfschwimmer”. With his support we were able to add the Ref. 3646 / Type B “Radiomir Panerai” into our database last year – read more here.

Actually, the photo is not new to us. It has been published many years ago in Cajus Bekker’s book “Einzelkämpfer auf See” in 1968 and again in 1978. However, there were never published names of the frogmen in the captions of these two books. Until now: The backside of the original paper photo showed pencil written names of the men which were captured in the photo, which helped us now to identify and link them to other photos in our archives. We have published a photo, taken from a slightly different perspective, showing the same training scene, in chapter V of our book “History2” on page 460.

The photos were taken in the summer of 1944 on the island of San Giorgio (south-west of Venice harbour), showing the training in hand-to-hand combat, which was a fixed part of their training along with other different sporting disciplines. One of the frogmen in the photo is the first owner of the Ref. 3646 / Type B watch on the left.

Read more on the activities on the island of San Giorgio in chapter I of our book “History1” including rare historic documents and aerial photographs from the Allied Forces intelligence.

Our special thanks to the frogman’s grandson who provided the photo above (including the additional informations on ist backside in shape of handwritten names), on which he placed the Ref. 3646 / Type B “Radiomir Panerai” of his grandfather. [Ralf Ehlers & Volker Wiegmann]

We recently added another unknown watch into our database – yet another piece of the puzzle surfaced: a Ref. 3646 / Type C with “Radiomir Panerai” sandwich dial, being watch #63 in our records of watches matching the criteria of the 3646 / Type C.

The Ref. 3646 / Type C “Radiomir Panerai” will be auctioned on 21 May 2022 at Dr. Crott’s 106th auction in Mannheim/Germany. It has been consigned by the family of the German “Kampfschwimmer” veteran Heinz Greten. Further info on auction lot 156 can be found here.

The watch appears with an unpolished case with a matching high bezel, typical for watches with “Radiomir Panerai” sandwich dial. The watch comes with a tubular shaped Rolex Oyster crown (Type 13). Inside the watch is a Rolex Cal. 618 / Type 1 movement with typical decorations and engravings on the bridges (ROLEX 17 RUBIS / FAB. SUISSE). The inner caseback bears the typical Rolex SA hallmark, reference and case number known for 3646 / Type C watches, with “Half Polish” decoration. Both hands appear black painted and re-lumed. The inner caseback bear also watchmakers’ service marks.

Noteworthy:
The outer caseback of the watch bear engravings of the first owner, German “Kampfschwimmer” Petty Officer Hans Greten with the additional info Antwerpen, referring to a mission he took part in September 1944.

The mission (“Operation Bruno” – the attack of the Kruisschans floodgates in Antwerp) is documented in the book “Sabotage unter Wasser” written by Michael Jung (2004) on page 120-121, as well as a photo of Hans Greten on page 107. Further info on this frogmen mission is also found in the book “Das Kommando der Kleinkampfverbände der Kriegsmarine” written by Helmut Blocksdorf (2003), on page 181. The earliest documentation of the mission is dating back to 1956 in the book “…denn sie liebten doch das Leben” written by Cajus Bekker (chapter six, page 148-160), in which Greten is mentioned several times (all books are written in German language).

Features of the watch:
Reference: 3646 / Type C
Dial: “Radiomir Panerai” (sandwich)
Case number: 10102XX
Movement: Rolex Cal. 618 / Type 1

In our book “The References” 1930’s-1940’s the watches of the entire reference 3646 are featured in chapter II with more than six hundred pages in the chapters II.I-II.VII. The seven different variations (including the number group 3646 / Type C – page 248-397 – to which this watch belongs) can be found in our reference quickfinder on page 14-20.

Please note that the very rare campaign insignia 3rd degree (visible in the background of the second photo) is the (separate) lot 155 and is not included in the lot of the watch. Information on different probation and campaign insignia of the German “Kampfschwimmer” units can be found in our book “History2” in chapter IX.

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]

Phillips will feature a very rare Ref. 6154 “Small Egiziano” in their upcoming auction Geneva Watch Auction: XV. Between the different Vintage Panerai references, the 6154 is one of the rarest and most attractive because of its unique flat case design and only a small number of watches existing today. The watch appears with brown faded “Radiomir Panerai” dial, 8 mm Rolex crown and Rolex 618 / Type 1 movement. The auction lot includes a depth gauge and a rare underwater torch, known to be used by Egyptian frogmen in the 1950’s and 1960’s. Further info on this watch (lot 293) can be found here.

This particular watch can be traced back to the year 1995 when it was auctioned at Antiquorum in Geneva. Two years later, in 1997, it was published in the book “Militari da polso” on page 60. The watch was also published in our book “The References” (2009 edition, sold out) on page 197 and again – in detail – in our book “The References” 1950’s-1960’s on page 808-817.

Read the historical background on watches and instruments from Guido Panerai & Figlio used by the Egypt frogmen in chapter VII and IX of “The References” 1950’s-1960’s, including rare photos of an Egyptian frogmen wearing Guido Panerai & Figlio instruments (page 794, 1064 and 1068). 

The “Maserati” amongst Vintage Panerai references because of its flat, elegant and streamlined case, was auctioned in 2016 at Phillips Geneva Watch Auction: FOUR and remained under the surface since then.

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

A “Gamma” frogman who wrote history. A photo from 1998 which was a reminder not to miss the chance to capture Luigi Ferraro’s story in our book “The References” – together with the 3646 / Type B watch he was wearing during the “Operazione Stella” in 1943.

One of the few watches which can be followed back to the first owner, which is also a very famous one: Luigi Ferraro (M.O.V.M.). Not easy to capture as much as possible of his story in a part in the first volume of “The References”, which filled several books of Italian authors with hundreds of pages. Even in the first Panerai books, written by Giampiero Negretti in 1998, Luigi Ferraro’s famous missions in the mediterranean sea found their place to be mentioned.

To get in touch with the family of the veteran Luigi Ferraro (1914-2006) was a very intensive and exciting time during the research about his Ref. 3646 / Type B “Radiomir Panerai” with riveted plastic dial (chapter II.II page 190-203). Paolo Ferraro, one of Luigi Ferraro sons, provided excellent photos and made personal documents available for us to be featured in our book, which gave us the chance to illustrate the history behind his father’s watch.

In January 1943 Luigi Ferraro obtained his qualification to carry out underwater missions. Initially posted to North Africa to attack enemy targets in the Port of Tripoli, he had to leave the area and returned to Italy. In May 1943 he was posted to La Spezia, where he received instructions from commander Borghese for a new mission – this time not in North Africa, but in the eastern Mediterranean: the Turkish ports of Alexandretta and Mersina. Luigi Ferraro’s four “Stella” missions, for which he was awarded with the M.O.V.M., are described in chapter II.II (page 204-225).

Aside several tools of his time as a “Gamma” frogman, Luigi Ferraro’s 3646 / Type B “Radiomir Panerai” never changed ownership and remained a memorable piece for him and his family since he returned from war. The watch shows intensive proof of aging and is an example of how different these rare watches have aged after more than 70 years. The watch still has its original strap, as well as its original domed plexiglas crystal – intensively aged with countless fissures. Numbers, indices and the typical “Radiomir Panerai” lettering on the riveted plastic dial can still be made out at some points.

Luigi Ferraro’s watch has been recorded in our database in 2014, however the watch was known to us already years before. The Rolex 618 / Type 1 movement in combination with the small Oyster Watch Co hallmark, embossed on the inner caseback together with the reference and case number, is matching our criteria for being a watch of the Reference 3646 / Type B. The outer caseback bears a rare matriculation number, of which only a very few 3646 watches are known today. We have published further information about the different matriculation numbers on some of these watches in chapter II.III (page 301-303).

Luigi Ferraro’s 3646 / Type B “Radiomir Panerai” with riveted plastic dial is published extensively in chapter II.II (page 190-203) of the book “The References” 1930’s-1940’s.

More 3646 watches with an interesting history, related to their first owners and the missions they carried out during the Second World War, are introduced in chapter II.I (Ernesto Notari) and in chapter II.III (Licio Visintini). Enjoy reading!

Just a few days before the first success of the MT explosive boats on 26 March 1941 in Souda Bay, the 1st MAS Flotilla changed its name and became the 10th MAS Flotilla – the Decima MAS on 15 March 1941. Capitano di Fregata Vittorio Moccagatta was the new commander and divided the special weaponry – Mezzi d’Assalto – into two divisions:

The surface division – Mezzi di Superficie – under the command of Capitano di Corvetta Giorgio Giobbe (see photo on page 115, commander Giobbe wearing clearly visible a Panerai watch on his right wrist) had a fleet of various explosive boats (category MT, MTM, MTR, MTS, MTMS, SMA and MTL) for sabotage operations, based in La Spezia.

The underwater division – Mezzi Subacquei – under the command of Capitano di Corvetta Junio Valerio Borghese operated the diving School in Livorno, the SLC training base at Bocca di Serchio, the transport submersibles (Scirè and Ambra) and the frogmen of the “Gruppo Gamma”.

After the desaster at Malta in July 1941 (“Operazione Malta 1”), the Decima MAS was restructured. Capitano di Fregata Ernesto Forza became the new commander of the Decima MAS. The underwater division was given the name of the fallen inventor of the SLC, Teseo Tesei, now commanded by Junio Valerio Borghese. The surface division was given the name of the fallen commander of the Decima, Vittorio Moccagatta, now commanded by Salvatore Todaro. See page 116 with a historical chart of the new structured Mezzi d’Assalto as of October 1941:

Ernesto Notari became commander of the SLC training base at Bocca di Serchio. His Ref. 3646 / Type A “Radiomir Panerai” (with its unique engraved caseback) is documented on page 58 – 91.

Read more about the Mezzi d’Assalto on page 92 – 153 in chapter II.I of the book “The References” 1930’s-1940’s.

After the failed missions in August and September 1940, the Decima MAS returned to the eastern Mediterranean in order to make another attemp to attack the Harbour of Alexandria with SLC devices of the Mezzi d’Assalto: “Operazione G.A.3”, carried out by Tenente di Vascello Luigi Durand de la Penne and Capo Palombaro I Emilio Bianchi (SLC 221), Capitano Genio Navale Antonio Marceglia and Sottocapo Palombaro Spartaco Schergat (SLC 222), Capitano Armi Navale Vincenzo Martellotta and Sottocapo Palombaro Mario Marino (SLC 223).

What turned out to be one of the most famous SLC missions in the Second World War has been announced in the Italian War Bulletin N. 585 of the 8th of January 1942: “On the night of the 18th December assault craft of the Italian Royal Navy entered the Harbour of Alexandria and attacked two British battleships anchored there. It has only just been confirmed that a battleship of the Valiant class was seriously damaged and put into dock for repairs, and is still there.”

Bulletin N. 586 of the 9th of January 1942, added the following: “In the Operation conducted by assault craft fo the Royal Italian Navy in the Harbour of Alexandria and reported in yesterday’s Bulletin we now have definite further intelligence that, in Addition to the Valiant, a second battleship of the Barham class was also damaged.”

Winston Churchill announced in a speech before a secret session of the House of Commons on the 23rd of April 1942: “A further sinister stroke was to come. On the early morning of December 19 half a dozen Italians in unusual diving suits were captured floundering about in the Harbour of Alexandria… Four hours later explosions occurred in the bottoms of the Valiant and the Queen Elizabeth, produced by limpet bombs fixed with extra-ordinary courage and ingenuity, the effect which was to blow large holes in the bottoms of both ships and to flood several compartments, thus putting them both out of Actions for many months…”

Read chapter II.I of our book “The References” 1930’s-1940’s to find out what happened on 18 December 1941 (page 118-125).

Luigi Durand de la Penne was one of the famous SLC pilots of the Mezzi d’Assalto who wrote naval history in the Second World War. Luigi Durand de la Penne was born in Genoa, where he also died (11 February 1914 – 17 January 1992). He graduated from the Naval Academy in Livorno in 1934. He was one of the first crewmen of the 1° Gruppo Sommergibili who realized Teseo Tesei’s and Elios Toschi’s idea of a new, secret weapon in La Spezia: The SLC. At the training base Bocca di Serchio he was a member of the legendary group which founded the famous „Spirito del Serchio“.

The first remarkable milestones of his naval career was the rescue action of the transport submarine for SLC devices, the Iride: On 22 August 1940, in the Gulf of Bomba, the Iride was sunk by a torpedo released by a British Swordfish bomber. The air attack happened during an exercise, in shallow water, when four SLC teams were around, including  the officers Teseo Tesei, Gino Birindelli and Luigi Durand de la Penne. They started an immediate rescue action. Of the 12 Iride crewmen who survived, two died during an unsuccessful attempt to surface, nine were retrieved alive (two of them died soon, due to wounds), and one was too shocked to leave the sunken submarine. Luigi Durand de la Penne tried to persuade him to surface, and even gave him his own rebreather, but the seaman refused surfacing and died.

Luigi Durand de la Penne (3rd from left) together with the commanders of the 1st MAS Flotilla (Aloisi and Giorgini), surrounded by Stefanini, Bertozzi, Falcomatà, Tesei, Birindelli and Centurione.

The second milestone in Luigi Durand de la Penne’s naval career was the sinking of the British battleship Valiant. In December 1941, he was one of the “fab six” (Emilio Bianchi, his co-pilot; Antonio Marceglia with Spartaco Schergat and Vincenzo Martellotta with Mario Marino) that attacked the Port of Alexandria. As a result, four ships were disabled: the British battleships HMS Queen Elizabeth and HMS Valiant, the oil tanker Sagona and the destroyer HMS Jervis. Luigi Durand de la Penne was awarded the M.O.V.M. (the Italian highest military decoration awarded for valour “in the face of the enemy”). At the end of the war, Admiral Charles Morgan (the Valiant’s Captain at the time of the attack in Alexandria) wanted to confer himself the medal to Luigi Durand de la Penne in a ceremony in Taranto.

After 8 September 1943, Luigi Durand de la Penne was offered the opportunity to be released from prison and fight for the Allies. He accepted and returned to duty as a frogman. In June 1944, he participated in a joint Italian/British operation against the Germans (mission QWZ). A team of British and Italian divers sank the cruisers Gorizia and Bolzano before they could be used to block the harbour entrance. After the Second World War, Luigi Durand de la Penne stayed in the Marina Militare. He was promoted to Capitano di Fregata in 1950 and Capitano di Vascello in 1954. In 1956 he was appointed as Naval Attaché in Brazil.

Luigi Durand de la Penne‘s family donated decorations he was awarded during his career, and his Panerai watch to the museum at the COMSUBIN headquarters in Varignano / La Spezia. The Panerai watch, a Ref. 3646 / Type C with “Radiomir Panerai” dial has been recorded in our database in 2015. Enjoy reading more: Luigi Durand de la Penne M.O.V.M. is featured in chapter I (page 35), chapter II.I (page 94-123) and VIII.II (page 1016-1034) of our two “The References” books.

Sad news reached us last weekend from Saxony. Manfred Lau, born 1925, who told us about his experiences in the last months of the Second World War, has recently passed away at the age of 96. His personal story became Chapter VI in our book “History2” and will remain as one of the few stories from surviving “Kampfschwimmer” veterans, which we were able to publish ten years ago. We have been in contact with Mr. Lau since 2003 and have always been amazed by the many details of his training on the island of Le Vignole in the Lagoon of Venice, which he shared with us after more than 60 years passed. May he rest in peace!
