Notes

References 6050 and 5050 are identical except that Ref. 6050 (See lot 87) has a ?Super-Oyster? crown and Ref. 5050 has a traditional Oyster crown. The caliber 620, was created in 1936 and was in regular production between 1940 and 1951. This type of case is called ?Bubble-Back? by English-speaking collectors. The Italian collectors call the watch an ?ovetto? due to the olive like outline of the case. This watch is illustrated in ?Rolex, Collecting Wristwatches?, by Osvaldo Patrizzi, 2001 Edition, p 154.
