3646_no_hallmark_2_600x600Why do some Ref. 3646 watches come only with a six digit case number embossed on their inner caseback? Where did the Rolex hallmark and reference number go? In which of the seven different number groups of the Reference 3646 is this the case?

Our book “The References” 1930’s-1940’s answers these questions in two chapters by measurement results and illustrated cross-sections (page 537-551, 638-639 and 644-645). The coffee table shot on the left shows a Ref. 3646 / Type G with a technical illustration on page 618-619 in chapter II.VII.

Chapter II.V = Reference 3646 / Type E
(featuring four different watches on page 532-573).

Chapter II.VII = Reference 3646 / Type G
(featuring two different watches on page 608-645).

“The References” books are in stock and can be ordered in our bookstore. Enjoy reading!
