Watches from Guido Panerai & Figlio are deeply connected to the history of the Royal Italian Navy during the Second World War. In our book “The References” we have included an overview of the missions of the “Decima” aside the legendary watches, which were an important part of the units of the underwater (“Mezzi Subacquei” / “Gamma” frogmen and SLC) and surface (“Mezzi di Superficie” / explosive boats) special forces of the Decima MAS (“Mezzi d’Assalto”).

After the disaster 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 (the photo below shows a historical chart of the new structured Mezzi d’Assalto as of October 1941).

Chapter I and II of the first volume (1930’s-1940’s) carry the history of a new weapon – the SLC slow running torpedo, called “maiale” – and the men who trusted on the watches from Guido Panerai & Figlio during their dangerous missions in deep and darkness of the mediterranean sea. Because of the significance of the fascinating history behind these watches, we have dedicated our book “The References” to the inventors of the SLC, Teseo Tesei and Elios Toschi.

Chapter II of “The References” features some of the rarest Panerai watches owned by famous and high decorated Italian veterans. The first watch of the Reference 3646 / Type A, featured in chapter II.I, belonged to Admiral Ernesto Notari. He was awarded with the Silver Medal for Gallantry at War (M.A.V.M.) for the mission B.G.6 in May 1943.

The documentation of the watch (see above page 70-71) and the history of Ernesto Notari, including a summary of the “Mezzi d’Assalto” missions until 8 September 1943 can be read from page 58 to 153 in chapter II.I.

Chapter II.II, about the watches of the Reference 3646 / Type B, features the watch of the legendary “Gamma” frogman Luigio Ferraro. He was awarded with the Gold Medal for Gallantry at War (M.O.V.M.) for his “Stella” missions in the eastern part of the mediterranean sea in 1943.

The documentation of the watch (see above page 190-191) and the history of Luigi Ferraro can be read from page 190 to 225 in chapter II.II.

A watch of the Reference 3646 / Type C which belonged to the SLC pilot Licio Visintini is featured in chapter II.III. Visintini took part in several missions against the allied fleet in Gibraltar. After surviving from mission B.G.3 and B.G.4 in 1941, Visintini returned undercover to Gibraltar in June 1942 where he built the core of the “Orsa Maggiore” on board the tanker Olterra – the hidden base for the SLC units of the “Decima” in the bay of Gibraltar. Mission B.G.5 turned into a “mission with no return” for Licio Visintini in December 1942…

The documentation of the watch (see above page 352-353) and the history of Licio Visintini can be read from page 350 to 397 in chapter II.III.

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.

What happened after 1 January 2016 when we “paused” counting new entries in our database for a moment to complete our book set “The References”? We continued to count and still do that – since 2003 (…21 years ago). January 2024 was a good time to pause again and see how our records have changed in numbers of known watches in our database. The total number of all historic Panerai watches in our database from the 1930’s to the 1960’s has grown to 452 known watches.

Back in 2016 we had 211 entries of the Reference 3646 in our database (seven different number groups, from 3646 / Type A to 3646 / Type G). Since then, 55 watches of the References 3646 have been added into our records, making a total of 266 watches of the reference 3646 today. Find an interim status on 1 January 2024 below:

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.

Sotheby’s New York will auction a rare Ref. 3646 / Type B with riveted plastic dial – read more at their website here.

This specimen is one of only 21 Ref. 3646 / Type B watches known in our database until today. It has been recorded in 2013 and still remains the watch with the lowest case number within all known Ref. 3646 / Type B watches, bearing the small Oyster Watch Co hallmark on the inside of the caseback (“full polish” decoration) with its seven-digit casing reference number and the reference number 3646. You can read more on our 3646 caseback classification here.

The watch is fitted with a riveted plastic dial, which has a smaller diameter than the sandwich dials, visible by the little gap between dial and (high) bezel. It bears the famous “Radiomir Panerai” writing below 12 o’clock. The surface of the plastic dial has become distorted over time. The luminous material under the surface in the numerals and indices appears lightly raised, while the other areas have become recessed (see also photo here).

The watch is fitted with a Rolex crown (Type 13) with “Oyster Patent +” lettering. The steel hands on this watch have become competely skeletonized. The dodecagonal caseback of the watch does not have an outer engraving. The 47 mm steel case has the typical breadth of the curved strap loop, a common feature on watches from the early series (Type A to Type C) visible in the photo below.

Features of the watch:
Reference: 3646 / Type B
Dial: “Radiomir Panerai” (sandwich, riveted plastic dial)
Case number: 1009XXX
Movement: Rolex Cal. 618 / Type 1

We have featured this watch in our book “The References” 1930’s-1940’s in chapter II.II on page 173-189. It was one of several historic Panerai watches Hammer provided to us in 2014 to be featured in our books. We hope our friend’s beloved 3646 will find a good new home and that it remain surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]
