Hands-on review: Jaeger-LeCoultre Polaris Mariner Memovox

Pinterest LinkedIn Tumblr +

Underwater, accomplished and amateur divers alike need to rely on equipment that is impeccable both in terms of precision and safety. While previous models of the Polaris automatic only came with 100m water resistance, the dive styled watch is now a dive ready watch with the upgraded 300m water resistance. The new Jaeger-LeCoultre Polaris Mariner Memovox is also equipped with this update in an attractive blue sunburst dial.

The Case and Dial

The Polaris Mariner Memovox with its unidirectional, notched rehaut, skeletonized hands of different shapes and colors, power gauge and water resistance of up to 300 meters adhere to the ISO 6425 standard. The sports watch is fitted with a brushed and polished bracelet that is well-built and comfortable on the wrist.



Another differentiating element of this new model: An orange ring that is only visible when the crown at 3 o’clock is not screwed on, reminding the diver that they have not adjusted the rehaut, essential for predicting their ascent and respecting the correct decompression stops.

On this new model, the Super-LumiNova® numerals and hour-markers are dressed in brilliant white, and provide necessary visibility under low-light conditions.



The steel watch measures 42mm in diameter and 15.63mm in height. The watch is relatively thick due to its thicker rasied dome crystal which is in part necessary for higher pressure ratings. The alarm movement is also thicker than the usual time-only automatic movements and passes on the thickness to the case.


The blue dial has a fume like pattern with a lacquered texture. It is fit with Bâton à facette hands, or skeleton hands and uses a inner disc as an hour marker. The hour markers are polished rhodium-plated appliques complemented by an inclined date wheel.

The Movement

The watch uses the Jaeger-LeCoultre Caliber 956, an automatic movement with 45 hours power reserve. The 7.47 mm movement beats at 28,800 vph and is equipped with an alarm and date function.


Concluding thoughts

Priced at S$25,900, the watch is on the pricier side of the Memovox models. In comparison, the new Master Control Memovox is priced at S$17,300. The price difference is the premium on dive watch water proofing and dive watch features. That said, the proportions are also on the larger side at 15.63 mm vs the classic Memovox at 12.4 mm.

For those looking for a Memovox and a dive watch as an update to the deep sea alarm, the new Mariner Memovox is an excellent choice. Even thought it has a larger case dimension, it wears comfortably and has a very attractive dial.
