Vintage Jaeger-LeCoultre Memovox Automatic Alarm, Date window, Cal. K825, Silver Dial from 1963
Jaeger-LeCoultre gave the world its first automatic alarm wristwatch in 1956, and three years later added a date. That second step produced the Calibre K825, and this 1963 Memovox is built around it. If you’re looking for a vintage Jaeger-LeCoultre that does more than tell the time, this is one of the most meaningful places to start.
The 37mm stainless steel case is the “Jumbo” Memovox size, with two crowns: one sets the alarm, the other winds and sets the time. The silver dial has a brushed central disc that turns to set the alarm, marked by a black triangle. Around it are applied faceted baton markers, small lume dots on the minute track, and a date window at 3 o’clock. The dial shows light, even spotting and aged lume, which suits a watch of this age. Nothing about it looks redone.
Turn it over and the Memovox stamp sits on the caseback, with a LeCoultre & Co. “Acier Inoxydable” signature inside. The bumper automatic K825 is signed Jaeger-LeCoultre and is a fine example of 1960s Swiss horology: a self-winding movement with a hammer alarm and date, made in-house at Le Sentier. A genuine collector’s watch from the golden age of Swiss automatic watches.
