Introducing the Jaeger-LeCoultre Polaris Mariner Collection


Jaeger-LeCoultre, Grande Maison of impeccable Swiss watches pays homage to its alarm wristwatch legacy and its contribution to robust, reliable dive watches with two new additions to the Jaeger-LeCoultre Polaris collection. Both wristwatches come with a fully ISO 6425-compliant specification and boast an almost identical aesthetic on the outside. On the inside, however, it all changes…


The Polaris is one of the most loved wristwatch collections by Jaeger-LeCoultre. Its history harkens all the way back to 1959 when the watchmaker developed the first ever Memovox model, complete with an alarm function that warned a diver when to resurface from his exploration underwater. The design was strengthened even further in 1968 when JLC launched the Memovox Polaris, complete with a triple layer caseback feature for enhancing sound transmission. It also featured an internally rotating bezel along with the innovative alarm function. For its time, the diving watch offered something highly unique during the 1950s when professional and amateur divers had very few technologies to help them keep track of remaining time underwater.

Lending design cues from the legendary Memovox Polaris watch from the past, these two new iterations from the collection go by the name of the Jaeger-LeCoultre Polaris Mariner Memovox and the Jaeger-LeCoultre Polaris Mariner Date.


Shared Polaris features

The two new 42mm Jaeger-LeCoultre Polaris watches look stylish on the wrist whether worn with a diving suit or something more formal, but first and foremost they are quintessential diving tools that the company has equipped with features to help with keeping the internals of the watch dry. Techniques have been thoroughly researched and refined over the last seven decades to enable this. Firstly, both watches have a 300-meter water-resistant case and a box-style glass lens that echoes the look of the original 70s Polaris watch. In addition to this, the crown used to access the notched inner bezel is screwed down to minimise the risk of water seeping through the joints of the case. Furthermore, an orange band will notify the wearer should the crown not be fully engaged in the locked-down position. From the outside, the only difference between the two models is the third crown situated on the right side of the Polaris Mariner Memovox alarm watch (the top crown controls the alarm, the middle sets the inner bezel, and the bottom sets the time), while the Polaris Mariner Date features just two push-pieces at 2 and 4 o’clock.

Where Jaeger-LeCoultre really succeeds in capturing the beauty and finesse of this popular diver watch, however, is its choice to design these two models with a stunning gradient blue dial that gradually changes from a light blue to a deep midnight blue around the edge of the display. Three concentric circles are also executed in different finishes; the central ring is sunray-brushed, surrounded by a subtle graining texture, and an outer opaline rotating bezel. Trapezoid indexes and Arabic numerals treated with luminous material make referencing the time underwater or during the night an effortless task. During the day the seconds hand is identifiable by a vivid orange colour, while the central hands illuminate in different shades by night to easily differentiate one from another.


The Jaeger-LeCoultre Polaris Mariner Memovox

There are a few ways in which JLC pays homage to its original Polaris design in the new Mariner Memovox. To start with, the Calibre 956 which powers the watch, directly descends from the first in-house alarm movement developed by Jaeger-LeCoultre in 2008. A transparent caseback showcases the beautiful decoration and performance of this perfectly arranged movement through the rear of the case. This includes a view of the movement’s strike-works, Cotes de Geneve decoration and an open -worked heavy metal rotor on motion. The “school bell” sound of the Memovox alarm, however, remains completely unchanged.

Recap of the Polaris Mariner Memovox watch features:

42mm steel case – 300-meter water resistance – gradient blue dial with luminous hours and different luminous-coloured hands.

Function: hours, minutes, seconds, date, unidirectional rotating bezel, alarm

Movement: Calibre 956 – 45-hour power reserve – open caseback

Stainless Steel bracelet with folding clasp


The Jaeger-LeCoultre Polaris Mariner Date

The Polaris Mariner Date features a running time indicator on the seconds hand, along with legible minutes, hours and an instantly jumping date display at 3 o’clock. Of course, a thick white line which accentuates the first 15 minutes of dive time on the bezel is a vivid feature that sets the new models apart from their ancestor, along with splashes of orange colour, which bring the new collection into a more contemporary realm of timekeeping. The integrated stainless steel bracelet (as with the Polaris Mariner Memovox) is a refreshing update from the original rubber strap. The time and date version of the Polaris without the alarm function features a top push-piece that controls the bezel and the bottom push-piece which alters the date and time. The Calibre 899 powers this version, offering up to 70 hours of power reserve and a flawless performance, again, put on show through a sapphire caseback.

Attesting to the high standards of manufacture adhered to at Jaeger-LeCoultre, actor Benedict Cumberbatch recently sported the Mariner Memovox on his wrist as he learnt the skill of freediving on Rakino Island in New Zealand. The short film “In A Breath” saw the actor and JLC ambassador hold his breath for impressively long durations underwater, whilst timing himself with the reliable Polaris Memovox.
