The history of this Jaeger-LeCoultre Memovox
This Jaeger-LeCoultre is one of the most emblematic mechanical alarm watches in Swiss watchmaking. Launched in the early 1950s, it addressed a unique need at the time: providing a mechanical audible reminder directly on the wrist. Reference E 855, produced in the 1960s, marks a key step in the evolution of the collection by integrating automatic winding and the date function, while preserving the functional and elegant DNA that has made the Memovox a favorite among enthusiasts and collectors.
Case, movement and bracelet
This Memovox ref. E 855 is powered by the Jaeger-LeCoultre manufacture calibre K825, a mechanical automatic bumper movement introduced in the late 1950s. Comprising approximately 241 components, it beats at 18,000 vibrations per hour and offers a power reserve of around 45 hours. Its alarm mechanism relies on a hammer striking directly against the inner caseback, designed to optimize sound diffusion. The 40 mm stainless steel case features two “JL”-signed crowns, allowing separate adjustment of the time and the alarm, while its screw-down caseback plays an essential acoustic role in the chime.
Why this watch
This Jaeger-LeCoultre stands out for its perfect balance between mechanical innovation and vintage design. Its smooth black dial, rare for this reference, lends it a discreet and timeless elegance. The applied indices, luminescent dauphine hands, date window at 3 o’clock, and the central rotating alarm-setting disc (an emblematic Memovox signature) make it a watch that is both highly legible and functional. An ideal piece for vintage watch enthusiasts seeking an iconic and technically accomplished model.
