Jaeger-LeCoultre - Polaris Mariner Memovox and Polaris Mariner Date

Jaeger-LeCoultre is expanding its Polaris collection launched in 2018 with two new models identified by the Mariner name to remark that they offer fully ISO 6425-compliant specifications, a requirement for professional diver's watches.

Both the Polaris Mariner Memovox and the Polaris Mariner Date are housed in 42 mm stainless steel cases featuring the key design codes of the Jaeger-LeCoultre Polaris cases with taut lines, glass-box crystals, and alternating brushed and polished surfaces. Water-resistant to 30 bar (approximately 300 metres / 990 feet), they are equipped with a crown used to set the notched inner-bezel is screwed-down to avoid any unintentional movement. 

The orange security band serves as a reminder for the wearer to screw down the crown to prevent water and dust from entering.

Their blue-gradient dials comprise three concentric circles finished in different textures (sunray-brushed central disc, grained middle ring, opaline outer ring) and featuring bold trapezoid-shaped indexes and three Arabic numerals. The opaline outer ring serves as the unidirectional rotating bezel.

The hands, indexes and numerals are filled with SuperLumiNova to enhance legibility in poor light conditions.

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.

The Polaris Mariner Date offers the classic diving-watch functions of hours and minutes, with a running time indicator (seconds hand) and unidirectional inner bezel, and the addition of an instantly-jumping date display. The upper crown operates the inner bezel while the lower one is used for setting the time and date.

It is powered by the Jaeger-LeCoultre Calibre 899 beating at a frequency of 4 Hz (28,800 vibrations per hours) with a power reserve of 70 hours. The retail price of the Jaeger-LeCoultre Polaris Mariner Date is Swiss Francs 10,600.

The Polaris Mariner Memovox features the recently revised Calibre 956, a self-winding movement with alarm function.

Through the transparent sapphire crystal, it is possible to observe the hammer in action producing the signature “school bell” sound. The gong is attached to the case side. 

The open-worked heavy metal rotor ensures an unobstructed view of the strike-works and the Côtes de Genève decoration matching the fine finishing on the movement plates.

The three-crown configuration is the same 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.

The price of the Jaeger-LeCoultre Polaris Mariner Memovox is Swiss Francs 16,900. jaeger-lecoultre.com
