This case shape is called ?Bubble-back? or ?Ovetto? by collectors. Italian collectors use the word ?Ovetto? due to the olive shape of the case, while American, northern European and Asian collectors call these watches ?Bubble-Back? due to the heavily domed case back. A similar watch is illustrated in ?Rolex, Collecting Wristwatches?, by Osvaldo Patrizzi, 2001, p. 145.
