Jaeger-LeCoultre Polaris Mariner Memovox

The Jaeger-LeCoultre Polaris Mariner Memovox Surfaces

October 12, 2020

Paying homage to its distinguished diving watch legacy and drawing upon more than a century of expertise in chiming watches, the Grande Maison introduces Jaeger-LeCoultre Polaris Mariner – adding a new high-performance timepiece to the sporty-elegant Jaeger-LeCoultre Polaris collection.

Thanks to the Manufacture’s expertise in striking movements, the Memovox has become the reference in wristwatch alarm calibers since it was introduced 70 years ago – employed in watches designed for both urban lifestyles and underwater sports.

Back in the 1950s, scuba diving was a risky and challenging military activity. The only tool available for diving was the watch, which created a strong demand for professional diving timepieces. In 1959, Jaeger-LeCoultre responded with a unique solution, a self-winding Memovox movement, which provided an aural warning that it was time to return to the surface. This was followed in 1968 by the Memovox Polaris, with an internal rotating bezel as well as the alarm, and a triple-layer caseback for better sound transmission.

Jaeger-LeCoultre Polaris Mariner draws on this diving watch heritage, presenting a new model that unites fully ISO 6425-compliant specifications with the sporty aesthetic of the contemporary Jaeger-LeCoultre Polaris collection.

The 42mm case features the key design codes of the Jaeger-LeCoultre Polaris cases with their taut lines, glass-box crystals, and dynamic mix of brushed and polished surfaces. In keeping with its purpose as a high-performance diving watch, the Jaeger-LeCoultre Polaris Mariner case is water-resistant to 300 meters (30 bar). Furthermore, the crown used to set the notched inner-bezel is screwed-down to avoid any unintentional movement, with the addition of an orange security band to warn divers when it is not fully screwed down.

Distinguished by their rich gradient-blue color, the Jaeger-LeCoultre Polaris Mariner dial also remains true to the contemporary Jaeger-LeCoultre Polaris aesthetic, comprising three concentric circles finished in different textures and featuring bold trapezoid-shaped indexes and four Arabic numerals. The central disc of the dials is sunray-brushed, complementing the subtle graining of the middle ring and the opaline finish of the outer ring, which serves as the unidirectional rotating bezel.

The hands, indexes and numerals are filled with Super-LumiNova to ensure excellent legibility in low light, as required of all diving watches. However, Jaeger-LeCoultre has gone a step further, maximizing divers’ safety by using different colors to distinguish the hour and minute hands. The running seconds hand is tipped in orange for daylight visibility, with a central luminescent section to avoid any possibility of confusion with the other hands.

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, Caliber 956, is also a direct descendant of Jaeger-LeCoultre’s first automatic alarm watch calibers. 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 caseback, to which the gong was attached; however, the Jaeger-LeCoultre Polaris Mariner Memovox has a transparent sapphire caseback, 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 rose gold 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.
