This Vintage JCL Memovox is the watch that made the mechanical alarm a proper complication rather than a novelty. Jaeger-LeCoultre launched the line in 1950, and this US-market example - signed simply "LeCoultre" on the dial, as they were for the American market.

The case measures 34.5mm across and 38.3mm lug to lug, 10.7mm thick, in 10K gold filled with a polished bezel and faceted lugs. Two crowns sit on the right flank — the upper one sets and winds the alarm, the lower one the time and date. The case back is the classic screw-down type. The dial is a two-tone silver, brushed on the outer chapter and sunburst at the centre, with applied gold rectangular markers carrying engraved Arabic numerals and small tritium dots on the minute track. A gold triangle on the inner alarm disc marks the set time, the date sits framed at three, and the gold hands and slim central seconds finish it cleanly.

Inside is the LeCoultre Caliber K911, a manual-wind alarm movement with 17 jewels running at 19,800 vibrations per hour. Wind the alarm barrel, set the triangle, and the hammer strikes against the back of the case - a mechanical buzz, not a beep, and the reason these are still worn daily sixty years on. Serviced and running as it should, alarm included.
