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, seven years ago, 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-G).

In our new 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 can be found in our reference quickfinder on page 14-20. The coffee table shot on the left shows one of seven specimen of the Ref. 3646 / Type C, introduced on page 322-349. Read also the extensively documented story of Helmut Rösel, first owner of this watch, in chapter IX of our book “History2”. Each of the seven variations of the reference 3646 are published here:

Chapter II.I = Reference 3646 / Type A
(featuring two different watches on page 50-169).

Chapter II.II = Reference 3646 / Type B

Aside numerous photos and technical illustrations of these 30 different watches, we have also published several yet unreleased historic photos of frogmen wearing watches of the reference 3646 during the Second World War.

One of these rare photos shows “Kampfschwimmer” Werner Bullin on page 275 in chapter II.III, wearing his 3646 with “Radiomir Panerai” dial. The coffee table shot on the left shows this photo which was taken at Piazza San Marco / Venice in summer 1944. Another rare photo has been introduced earlier here. Read the extensively documented story of Werner Bullin and Heinz Günter Lehmann over the 75 pages of chapter I in our book “History1”.
