The famed Jaeger-LeCoultre “Memovox” (voice of memory) was introduced in 1950, quickly gaining traction as one of the most desirable and reliable alarm wristwatches on the market. A center disc with an arrow is operated by a second crown typically found at 2 o’clock, allowing the alarm function to be quickly and easily set. In an era where sports diving was gaining more and more popularity (indeed, advertisements of the era branded the E859 as “pour l’homme d’action” or “for the man of action”), Jaeger-LeCoultre’s response was to launch a unique, oversized, automatic waterproof divers' wristwatch with an alarm function.
Their goal was to offer both visual (inner bezel) and auditory (alarm) timers for maximum diver safety. To do so, the firm created a patented case back, which optimized the alarm’s sound transmission under water. The outer case, with its 16 holes, allowed for the alarm tone to be heard and also felt on the wrist, while the inner case sealed and protected the movement. The watch featured three crowns, each with the cross hatch pattern characteristic of Super Compressor watches: the first for time setting, the second to rotate the inner bezel for dive timing, and the third to rotate the inner disc with arrow to set the alarm.
Known in the United States as the Polaris, and in the European market as the "Skin Diver Memovox", the reference E859 was made in 1714 total examples. The present European E589, signed Jaeger-LeCoultre on the dial, is amongst the finest examples to come to market. Well-preserved with a sharp case that in our opinion has never seen a polishing, its beautifully aged dial is flawless, with all luminous material original and fully intact.. The beauty of the case’s design is enhanced by the presence of the original and rarely seen rounded, domed crystal – most surviving examples are instead fitted with service crystals with a sharp edge.
