Sotheby’s New York to auction a Ref. 3646 / Type B
by Volker on Nov.25, 2023, under Watch Point
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]

“Il cavallo di Troia” – the secret SLC base
by Volker on Nov.23, 2023, under Allgemein
Enemy ships in the harbour of Gibraltar have been in the sight of the Royal Italian Navy since September 1940. After several attacks by “Gamma” frogmen and SLC units, ideas to build a secret base of the Decima MAS were realized in the second half of the year 1942. Convoy ships for the United States were beginning to arrive in quantity. The numbers of potential targets at anchor in the Bay of Algeciras were growing almost daily.
Earlier in 1942, a base for the Decima MAS “Gamma” frogmen was established in the Villa Carmela near La Linea from where several missions were carried out against British merchant ships (see page 126-131 / chapter II.I). During the months of shaping Villa Carmela into an advanced base, the idea for a bigger and much more effective operation had taken form in the mind of Licio Visintini, one of the SLC pilots of the mission B.G.4 in September 1941 (see page 374-381 / chapter II.III) which was carried out from the submarine Scirè.
Before the new base was ready for action, each attack at Gibraltar had required a long submarine voyage, air and land transportation of the attack-teams, the shipping of supplies and weapons, arrangements for rendezvous, an approach by submarine, and finally the task of smuggling the survivors back to Italy thru neutral Spanish territory.
Licio Visintini’s idea became real with turning the anchored ship Olterra inside the pier of Algeciras into a secret base for SLC missions. Visintini and further technical specialists replaced the original crew of the Olterra. An assembly workshop for the SLC devices (which arrived in sections, declared as spare parts for the damaged ship) was established in the hull. A portside cabin of the Olterra became the observation post with an excellent view of Gibraltar harbour. Finally, a folding door on the port side bow (see coffee table shot of page 386-387 /chapter II.III) became the exit door for the SLC units below waterline to reach their targets – and to return back into the hull of the Olterra. After months of intensive work in total secrecy, the inconspicious ship Olterra was turned into a Trojan Horse – “il cavallo di Troia” – and six men were ready for action with their SLC devices.
The Olterra was starting point of the following SLC missions against enemy ships in the bay of Algeciras / Gibraltar harbour: B.G.5 (7/8 December 1942), B.G.6 (7/8 May 1943) and B.G.7 (3/4 August 1943). Our book “The References” 1930’s-1940’s features two Ref. 3646 watches which were used during these missions.
The Ref. 3646 / Type A “Radiomir Panerai” watch of Ernesto Notari is featured in chapter II.I (page 58-91 / see coffee table shot on the left) – more on this watch and its history can be found here. The Ref. 3646 / Type C “Radiomir Panerai” watch of Licio Visintini is featured in chapter II.III (page 350-367) – more on this watch and the history behind can be found here. The new “The References” books can be ordered only in our bookstore.
Enjoy reading!

18 November 1944 – today in history…
by Volker on Nov.18, 2023, under Allgemein
Read chapter VII of our book “History2” to find out what happened on 18 November 1944. Rare documents helped us to capture the history behind a Ref. 3646 / Type D “Kampfschwimmer” watch, which can be found in this chapter.
Beside photos from the years 1944 and 1945 showing the watch on the frogman’s wrist, as well as his identification papers and travel documents issued in Venice (see photo), helped us to reconstruct the route Hanns-Martin Kaufhold took to the mission grounds in the last months of the Second World War.
Read more about chapter VII of “History2” (70 pages, 58 photos, 6 technical illustrations) here. and here. You can purchase your copy of “History2” in our bookstore.

Visintini’s 3646 / Type C “Radiomir Panerai”
by Volker on Oct.20, 2023, 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.
Information on “The References” 1930’s-1940’s (first volume) can be found here.
Admiral Gigantesco’s Ref. 6152/1 is up for auction
by Volker on Jun.06, 2023, under Allgemein
Aguttes will auction a Ref. 6152/1 “Luminor Panerai” with unique caseback engraving dedicated in the year 1983 to Admiral Cataldo Gigantesco.
We know this watch since June 2007 during a Panerai collectors meeting in Tuscany, where it submerged soon after for years and now surfaced for sale online at Aguttes (France). It is part of our database since Marco, son of the Admiral, showed us the watch 16 years ago (see photo on the left).
You can find more info on this rare Ref. 6152/1 with Rolex Cal. 618 / Type 4 movement and the unique engraving on its caseback at our Watch Point.
Aguttes to auction an Admiral’s 6152/1
by Volker on Jun.06, 2023, under Watch Point
Aguttes (Paris/France) will auction a Ref. 6152/1 “Luminor Panerai” with Rolex Cal. 618 / Type 4 movement and engraved caseback from 14 to 28 June online here (Lot 5).
This Ref. 6152/1 is in our database since June 2007, when we took the photos in this posting, during the annual Club Panerai collectors meeting in Viareggio/Italy. Back then, Marco, son of Admiral Cataldo Gigantesco, showed us the watch of his father. Aguttes has published detailled information on Admiral Gigantesco’s career at the Marina Militare / G.O.I. which led to the unique engraving on the caseback of the watch in 1983 here.
The Rolex movement of the watch with “Luminor Panerai” dial is a typical Cal. 618 / Type 4 version with incabloc shock protection and 17 jewels. The watch is equipped with so-called “Double Pencil” hands. The crown-protecting device of this watch is signed “BREV. ITAL.” and additionally numbered “5” on the underside.
Features of the watch:
Reference: 6152/1
Dial: “Luminor Panerai”
Case number: 124591
Movement: Rolex Cal. 618 / Type 4
Chapter VIII.II of our book “The References” 1950’s-1960’s is featuring similar watches like this specimen on auction at Aguttes, with Rolex movement and Panerai crown-protecting device, on page 922-1057. The unique caseback engraving has been illustrated and explained in our book “The References” 1950’s-1960’s on page 916-917. An overview about the “BREV. ITAL.” signatures on watches with crown-protecting device can be found on page 975.
Currently this Ref. 6152/1 is one of the 73 watches in our database with Rolex movement and Panerai crown guard. Read more on the known watches in our records here as of 1 Januar 2023.
We hope that this Ref. 6152/1 will find a good new home and remains surfaced in the Vintage Panerai collectors world. [Ralf Ehlers & Volker Wiegmann]
Training scene in the summer of 1944
by Volker on May.26, 2023, under Allgemein
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]
Inventors, pilots and a royal visitor…
by Volker on May.14, 2023, under Allgemein
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.

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”?

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, 53 watches of the References 3646 have been added into our records, making a total of 264 watches of the reference 3646 today. Find an interim status on 1 January 2023 below:
