“Operazione Stella” – Luigi Ferraro’s Panerai watch
by Volker on Aug.08, 2025, under Allgemein
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!
25 July 1941 – today in history…
by Volker on Jul.25, 2025, under Allgemein
Augusta (Sicily) 11 pm. The night of 25 July 1941 marks the beginning of the “Operazione Malta 1”, known by its disastrous result for the Mezzi d’Assalto, only three months after the first successful attack with MT explosive boats against British ships in Souda Bay (Crete) on 26 March 1941. One day later, in the early morning of 26 July 1941, the Decima MAS lost the head of the flotilla (Capitano di Fregata Vittorio Moccagatta), the head of explosive boats (Capitano di Corvetta Giorgio Giobbe), the doctor of the flotilla (Tenente Medico Bruno Falcomatà), SLC pilots (including their inventor, Teseo Tesei) and MT explosive boats pilots during the attack of the harbour of La Valetta (Malta).
On a side note of the history, the commander of the explosive boats / “Mezzi di Superficie”, Giorgio Giobbe (1906-1941), is well known for wearing his Panerai watch on his right wrist in a photo taken prior the mission against Malta (see page 111-115 in chapter II.I). More about missions and watches of the Decima MAS can be found here.
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 can be found here.

Visintini’s 3646 / Type C “Radiomir Panerai”
by Volker on Jul.03, 2025, under Allgemein
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 (engraved caseback and view into the movement shown above) and the history of Licio Visintini can be read from page 350 to 397 in chapter II.III.

Restart after the end of the Second World War
by Volker on May.09, 2025, under Allgemein
What brought about the demand for new and improved diver’s watches in Italy after the end of the Second World War? The answer to this question is inextricably intertwined with the history of the maritime special units, whose transformation from the Mezzi d’Assalto of the Decima MAS to the COMSUBIN took many years.
From 1947 to 1951, various divisions and bases were established, restructured and merged, finally settling on COMSUBIN (Comando Subacquei ed Incursori) in 1961. Varignano near La Spezia, headquarters of the COMSUBIN and, as of 1952, was and still is the base for the Scuola Incursori. One of the instructors in the 1950’s was Emilio Barberi M.O.V.M., shown on page 716 (MT explosive boat veteran of the mission against Souda Bay, March 1941, see also page 108-109 in chapter II.I). Read more in the intro of “The References” 1950’s-1960’s on page 705-719. These maritime special units were set up during the same period that Guido Panerai & Figlio was producing watches with the References 6152, 6154, 6152/1 and GPF 2/56, which are documented in chronological order in chapters VI to X. Compasses and depht gauges from these years are following in chapter XI, straps and buckles are closing this second volume of “The References” in chapter XII. Find an overview of all chapters in this book below:
Chapter VI = Reference 6152
(featuring three different watches on page 720-781)
Chapter VII = Reference 6154

Missions of the Egypt frogmen
by Volker on May.07, 2025, under Allgemein
The Red Sea, the Straits of Tiran, the Gulf of Aqaba, even the shores of Dakar (Senegal) and Abidjan (Ivory Coast) – target zones of the Egypt frogmen during the Suez Crisis, the Six-Day War and the Yom Kippur War.
Not very much has been ever published before about missions against enemy ports, ships and oil platforms during the conflicts between Egypt and Israel. In the mid-50’s, both Egyptian and Israeli special forces attended separate training courses in Italy to learn the skills for underwater missions from their Italian instructors. After our search for historical documents and with the support of a high decorated Egypt frogmen veteran we were able to put a spotlight on some of the missions carried out decades ago.
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 (second volume), accompanied with rare historic photos (page 794-795 shown in the coffee table shot above). The new “The References” books (two volumes with 696 pages each) can be ordered only in our bookstore. Enjoy reading!
