Jaeger-LeCoultre Memovox E876 – “Speed-Beat Jumbo”

The Memovox (“memory” + “voice” in Latin) is Jaeger-LeCoultre’s legendary mechanical alarm watch — and the E876 is one of my favourites.

Introduced in 1969, the E876 features the upgraded caliber K916, operating at 28,800 vibrations per hour — a major leap from the earlier K825’s 18,000 vph.
The K916 also introduced a full 360° bidirectional winding rotor, maximizing efficiency.

This “jumbo” edition was branded:

• GT (Grand Taille, or “big size”) for the French market,
• HPG (High Precision Guaranteed) for the U.S.

At 38 mm across (excluding crowns), its bold, cushion-shaped case captures the essence of 1970s design — offering a larger wrist presence than most JLCs of the time.

Ideal for wrists sized 17–22 cm.

Condition

• Lightly polished in the past; remains crisp with sharp edges.
• Dial and hands are absolutely beautiful.

Extras

• Originally sold on November 2, 1972, by Jaeger-LeCoultre Germany, Pforzheim
• Original JLC-signed NSA bracelet, almost no stretch, freshly serviced comfort clasp
  (Fits up to 19.5 cm wrist, bracelet alone worth €900–€1,200)
