Jaeger-LeCoultre Memovox 855 Automatic Steel Bumper Automatic circa 1965

The Jaeger-LeCoultre Memovox is one of the most iconic mechanical alarm watches ever produced—a practical complication housed within the elegant design language for which the maison is known. Introduced in the 1950s, the Memovox line was a technical triumph and became a signature piece in JLC’s rich history.

This particular example, the Ref. 855, dates to circa 1965 and features a 37 mm stainless steel case, a substantial and wearable size for both vintage and modern tastes. The silver dial remains beautifully preserved, accented by applied hour markers and the distinctive inner alarm disc. The heart of the watch is the JLC calibre K825, a revered bumper automatic movement that powers both the time and mechanical alarm functions.

What makes this piece especially desirable is its completeness: accompanied by the original box and papers, a rarity for a watch of this era. In addition, the watch was freshly serviced in June 2025, ensuring it is ready for reliable daily wear.

Highlights

• Original box and papers included—a rare complete set

• Freshly serviced (June 2025) and running flawlessly

• Desirable 37 mm stainless steel case—larger than typical vintage sizing
