Nicolas (amanico) kicks off a weekend discussion by showcasing his beloved LeCoultre Deep Sea Alarm US, Ref. E 857, a piece he frequently wears alongside its European counterpart. This thread explores the diverse horological choices of collectors, highlighting personal connections to timepieces beyond their market value. It offers a glimpse into the daily lives of enthusiasts and the watches that resonate most with them.

The Jaeger-LeCoultre Memovox reference E857 is a notable example of the brand's alarm watch production from the mid-20th century. This particular reference is distinguished by its larger case size compared to earlier Memovox models, reflecting a shift in design preferences during its era of production. It maintains the characteristic dual crown configuration, with one crown for time setting and winding, and the other for setting and winding the alarm function.
This reference typically features a stainless steel case, though gold-capped or solid gold variants were also produced. The case diameter measures 37mm, a substantial size for its period. It houses the automatic Jaeger-LeCoultre Caliber 825, an important development as it was one of the first automatic alarm movements. The movement provides a power reserve of approximately 45 hours and is protected by a plexiglass crystal.
The E857 appeals to collectors interested in historically significant alarm watches and the evolution of automatic movements. Its larger dimensions make it a more wearable option for modern tastes compared to some earlier Memovox references. Variants exist with different dial finishes and hour marker styles, offering variety within the reference.
