Celebrating THE SOUND MAKER™, the Jaeger-LeCoultre Polaris Mariner Memovox pays direct homage to Jaeger-LeCoultre’s first diving watches, with their robust capabilities and distinctive aesthetic.

The self-winding movement, Calibre 956, is also a direct descendant of Jaeger-LeCoultre’ first automatic alarm watch calibres. Introduced in 2008, it has been comprehensively revised by the Manufacture’s engineers for this latest generation of alarm watches. Previously, Memovox watches had a closed case-back, to which the gong was attached; however, the Jaeger-LeCoultre Polaris Mariner Memovox has a transparent sapphire case-back, allowing the wearer to watch the hammer in action. This demanded a complete redesign of the striking mechanism, with the gong now attached to the case side. The open-worked heavy metal rotor ensures an unobstructed view of the strike-works, its Côtes de Genève decoration matching the fine finishing on the movement plates. One important element remains unchanged, however: the signature “school bell” sound of the alarm, which lends such charm to the Memovox.

The Jaeger-LeCoultre Polaris Mariner Memovox retains the signature three-crown configuration of the earliest Memovox diving watches. The top crown controls the alarm, turning the central disc of the dial so that the triangular pointer lines up with the desired alarm time; the central crown operates the inner dive bezel and the lowest crown sets the time.
