Memovox Reference E855

Ref. E855

The Jaeger-LeCoultre Memovox E855 is a classic automatic alarm watch from the 1960s, notable for its distinctive angular bezel design and the K825 bumper automatic movement. It stands out for its larger-than-average case size (37mm diameter) for the era and its use of a 18,000 VpH beat, offering exceptional accuracy. This model was produced during a transitional period in automatic watchmaking, featuring a 'bumper' rotor design to avoid patent infringement. The E855 is also recognized for its water-resistant construction and the use of high-quality materials like 18K gold in European-market versions.
