In 1959, Jaeger-LeCoultre presented the first automatic diving watch with an alarm: the Memovox Deep Sea Alarm Ref. E857.

Its direct successor was the Jaeger-LeCoultre Polaris, presented in 1963, which is the reference E859 you see here. About 1700 pieces of this watch were made until 1970, before it came to the end of production.

The case diameter of 42mm was exceptionally large by the standards of the time, but perfectly suited for underwater legibility. Over time, the watch gained iconic status due to its simple design and rare complication. Today, the Polaris E859 is one of the most collectible wristwatches on the vintage market.

Housed under a hesalite crystal, the black dial features large tritium markers, a rotating inner bezel and a date window. Together with the three large crowns, the watch has a design you would expect from a classic vintage diver.

From a mechanical perspective, the Polaris is a masterpiece! JLC developed a unique triple caseback system that prevents the alarm sound from being muffled. For example, the outer caseback has 16 holes and acts as a resonator, amplifying the alarm sound. Thus, the sound is audible even underwater.

The three distinctive crowns are used to control the functions of the Polaris. The upper crown is used to wind the alarm and, when pulled out, to set the alarm time. The inner bezel can be turned with the crown at 3 o'clock. The lower crown is used to wind the movement and set the time.

Condition report.
Dial: immaculate condition without scratches, marks or other imperfections - original and intact tritium lume in hour markers and hands - signed "T SWISS MADE T".

Case: great condition - rarely worn - beveled lugs with perfect bevels and edges - intact and correct numbers inside the caseback - original crowns with typical cross-hatching.

Rarity, design, size, mechanics, historical relevance: The list of outstanding features of this timepiece is pretty long. It is not for nothing that the Jaeger-LeCoultre Polaris E859 occupies a special place among connoisseurs of sophisticated diving watches.
