Notes

Ref. 3372 was always sold with a "Bulletin de Marche". The stainless steel models are slightly different from the steel/gold and gold ones. In Italy in 1940, the cost of the center seconds model was 50 lire higher than the the one with subsidiary seconds. The caliber 620 was created in 1936 and was in regular production between 1940 and 1951. This watch is illustrated in ?Rolex, Collecting Wristwatches?, by Osvaldo Patrizzi, 2001 Edition, p. 135.
