This rare Jaeger-LeCoultre Memovox ref. 3151 is one of the earliest and most desirable alarm references produced by JLC during the 1950s: being the very first wristwatch with mechanical alarm from JLC. Minimalistic dial signature, 35mm size in steel and no date indication. The double-crown feature allows for winding and setting of time, as well as setting of the alarm of the manual wind cal. 489 movement. This particular example is one of the first Memovox to be produced, making it incredible rare. The watch has been restored by Atelier JLC in perfect manner. With its slightly offset horns it is an absolute beauty
