The Jaeger-LeCoultre Polaris Memovox, a limited edition of 1,000 pieces, channels the spirit of the 1968 original, which was the first diving watch equipped with a mechanical alarm. Housed in its 42-mm steel case, the triple-crown-operated alarm is driven by the modern Caliber 956, a direct descendant of the very first self-winding alarm movement, created by Jaeger-LeCoultre in the 1950s. The three crowns control the alarm function and time setting thusly.
The first winds the alarm function and then sets the alarm and date when it’s pulled out. The middle crown allows adjustment of the bidirectional inner rotating bezel. The lower crown pulls out to adjust the time on the central hour and minute hands on the black, vintage-inspired dial, which is enhanced with “aged patina” luminous details. Price: $12,600.
