Catalogue description
Dealer description — Craft & Tailored
This Jaeger-LeCoultre Automatic Memovox ref. E853 is one of the most desirable alarm references produced by Jaeger-LeCoultre from the 1950-60s. This reference employs the Cal. K815 movement, which is the very first automatic alarm movement and utilizes a "bumper rotor" for its automatic winding system. The double-crown feature allows for winding and setting the time, as well as setting the alarm. The top crown sets the alarm complication of the timepiece. This exquisite automatic Memovox features a noble 37mm case, making this creation oversized for its era. The case sits nicely on the wrist and has a classic and timeless appearance while remaining relevant by today's wristwatch sizing standards. This piece would make a great addition to an existing collection and be a great and classic timepiece as a stand-alone piece.

The case retains its original signed twin crowns that operate both the watch and alarm functions. The case back retains all of its original factory markings in crisp and visible condition, the case back exhibits some light tool marks which is common for these two-piece case backs. The watch comes supplied on a 2pc handmade leather strap. DIAL & HANDS The original silver two-piece dial is beautiful and in very presentable condition, featuring a subtle warm color-hue that accentuates the vintage aesthetic of the watch. The radium lume plots located around the center of the dial have aged to a dark brown/grey coloration and all remain intact, though some plots exhibit light degradation when inspected under U.V. light. The original dauphine-style hands are in great condition, under U.V. light inspection the hands appear to have been restored with tritium early into the watch life and are a light teal color.

Atlas type guide
Automatic (self-winding) watches
Self-winding watches use the wearer's motion to wind the mainspring. Abraham-Louis Perrelet and Breguet made 'perpétuelle' pocket watches with oscillating weights in the late eighteenth century, but the principle only became practical in the wristwatch. John Harwood patented a bumper automatic in 1923; Rolex's Perpetual rotor (1931) winding in one direction, and later bidirectional rotors (Eterna, Felsa Bidynator), established the modern form. Micro-rotors (Universal Genève, Buren) and peripheral rotors made automatic watches thinner.
What to look for
- A semicircular rotor turning 360° over the movement, or a 'bumper' weight that rebounds between springs.
- 'Automatic', 'Perpetual' or 'Self-winding' on the dial.
- A sealed screw-back case, since automatic watches are wound less often by the crown.
Dating clues
- Bumper automatics: 1923–c. 1955.
- Full rotors: from 1931 (Rolex); widespread after c. 1950.
- Micro-rotors: from 1954–1958.
