Introducing another Ref. 3646 / Type E watch which surfaced in Germany – this specimen appeared with painted brass dial.

Noteworthy is the well preserved original strap and “Bottle Opener” buckle, wich most of today’s surfacing watches don’t have anymore.

The “Kampfschwimmer” watch with anonymous painted brass dial has an unpolished case with a matching flat bezel. The onion shaped winding crown (“BREVET +” Type 11) can be screwed down onto the collar of the 47 mm cushion shaped case with soldered lugs.

Features of the watch:
Reference: 3646 / Type E
Dial: “Kampfschwimmer” (painted brass, anonymous)
Case number: 2608XX
Movement: Rolex Cal. 618 / Type 1 mod.

Inside the watch is a Rolex Cal. 618 / Type 1 mod. movement with typical decorations and engravings on the bridges (17 RUBIS / FAB. SUISSE). The blued steel hands appear untouched with original luminous material. The inner caseback is decorated with half polish. An overview of different decorative polish on the inside of the caseback (Type A – Type G) can be found on page 486 in our book “The References” 1930’s-1940’s.

Here we added another unknown watch into our database – yet another piece of the puzzle surfaced. Thanks to the collector who shared the photos and information with us!

Webb’s auction house from Auckland / New Zealand contacted us recently, providing information and photos of a yet unknown Ref. 3646 / Type E with “California Dial”. The watch appears with the matching flat bezel and both lead seals above and below the 47 mm cushion shaped case. The outer caseback is not engraved and the inner caseback is missing the Rolex hallmark and reference number, which is a typical feature of Ref. 3646 / Type E watches. The onion shaped winding crown (“BREVET +” Type 11) can be screwed down onto the collar of the 47 mm cushion shaped case with soldered lugs.

The “Error-Proof Radium Dial” by Rolex, with its railroad track minute markers and “SWISS MADE” signature at six o’clock, features half arabic and half roman numbers with luminous material applied from above.

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!

More than two hundred watches of the Reference 3646 are registered in our database today. Among all different Vintage Panerai models, the 3646 marks the reference with the most known specimen in our records. In 2009, 143 recorded watches were featured in the first (sold out) edition of our book “The References”. Within the entire serial number sequence of the reference 3646, we differentiate between seven different variations (3646 / Type A – Type G). The photo on the left shows a Ref. 3646 / Type D with anonymous “Kampfschwimmer” dial, which is featured in chapter II.IV (page 454-467).

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 following an intro on page 40-49. The seven different variations (3646 / Type A – Type G) can be found in our reference quickfinder on page 14-20.

Chapter II.I = Reference 3646 / Type A
