Don't miss the next drop
The Jaeger-LeCoultre Memovox is, without question, one of the most important watches in the post-war Swiss landscape. Born in 1950 from the Latin words memor and vox, “remember” and “voice,” the Memovox was JLC’s answer to a deceptively complex problem: how to put a mechanical alarm on the wrist in a package that worked, sounded great, and looked the part. They got it right immediately, and they kept getting it more right for the next two decades. By 1959 the manufacture had introduced the K825, a bumper-automatic alarm caliber that became the first automatic alarm wristwatch movement ever produced with a date complication. That movement powers the Reference E855, and it is arguably the definitive Memovox of the bumper era.
A bit of context for those new to the model. The “E” prefix stands for Etanche, JLC’s designation for a water-resistant case. The reference debuted in 1960 and ran in various dial and case configurations until roughly 1969, when the K916 high-beat movement and the Polaris-derived E875 took over. Across that decade Jaeger-LeCoultre offered the E855 in steel, gold-capped, 18k yellow gold, and 18k pink gold, and the dial menu eventually grew to include lacquered Lapis Lazuli, faux tortoiseshell “brownie” dials, two-tone tuxedo executions, and the worldtime variant. It was, as JLC’s own Heritage Director has said, the flagship dress piece of the 1960s for the manufacture, with enough variation that a collector could legitimately spend a lifetime on this model alone.
The K825 itself is a piece of horological history worth understanding. A “bumper” automatic means the rotor does not swing a full 360 degrees the way a Rolex or modern self-winder does. Instead, the oscillating weight rotates roughly 270 degrees and is caught by coiled springs at either end, bouncing back the other way. This was the workaround the industry adopted while Rolex’s full-rotor patent was still in effect, and JLC’s execution is widely considered among the finest of the genre. 17 jewels, 241 parts, separate barrels for the time and alarm trains, and that unmistakable hammer-against-caseback alarm tone that everyone who has handled one remembers. Approximately 45,000 to 67,000 K825 calibers were produced across the run, and that population had to cover the E855, the original Polaris E859, and the E861, so the survival rate of clean, original examples is genuinely thin.
This particular watch is a wonderful representative of the silver-dialed steel reference, with the applied JL logo at 12 and the layout we love best on the model. The two-tone “tuxedo” architecture pairs an outer silver chapter ring carrying the applied steel baton markers with a recessed, sunburst-finished silver center that holds the rotating alarm disc and its red enamel triangle pointer. The date sits in a framed aperture at 3 o’clock. The dial has aged honestly, with a soft moss-and-cream spotting that drifts across the outer ring, particularly in the upper half of the watch, while the inner recess remains noticeably cleaner. To us this is exactly the right kind of patina for a sixty-year-old alarm watch, the kind that proves the dial has never been touched by a refinisher and earns its character the only way a vintage dial can.
The case is a 37mm three-piece configuration with twin crowns at 2 and 4 o’clock, both signed with the Jaeger-LeCoultre logo as they should be. Edges remain crisp through the lugs and around the bezel, with light wear visible across the case sides and the lug tops consistent with a piece that has been worn but never aggressively polished. Flip it over and the screw-down caseback is engraved MEMOVOX above serial 1218400, with the inner caseback marked with the JLC reference details. The K825 visible inside is correctly signed JAEGER-LECOULTRE / FAB. SUISSE in gold lettering across the bumper rotor bridge, with movement serial 2028275, placing production firmly in the mid-to-late 1960s window.
Where this example earns serious bonus points is the bracelet. It arrives on its original signed Jaeger-LeCoultre NSA bracelet, the Swiss-made stainless steel reference (Pat. 434845) that JLC paired with the Memovox during this era. The clasp is engine-turned with the JL logo proudly engraved at the center, and the rolling-link construction has aged into that warm, broken-in patina that vintage steel bracelets develop only with time. Finding an E855 with its correct period bracelet is genuinely uncommon, and finding one with the bracelet in this kind of honest condition is rarer still. Most have been separated from their bracelets long ago and now wear leather. This one has stayed together, and we are leaving it that way.
Backed by our 2-year mechanical warranty and serviced in-house, this is the Memovox the model deserves to be remembered by. A bumper-automatic alarm watch with date from the manufacture that defined the alarm wristwatch, riding on its original bracelet, with a dial that has earned every bit of its character. To us this is the kind of watch that makes the case for vintage Jaeger-LeCoultre in a single glance, and a compelling argument that the most important alarm watch of the 1960s is still the smartest one to wear today.
