The Jaeger-LeCoultre Memovox Ref. E855 is a definitive vintage alarm watch produced between approximately 1960 and 1974. This 18k yellow gold model with a silver dial is highly regarded by collectors for its "jumbo" 37mm case size, which was considered oversized for the 1960s but remains contemporary by today's standards.

• ΚΑΣΑ: 37mm diameter solid 18k yellow gold with a lug-to-lug length of 45.5mm and 18mm lug width.

• Μηχανισμός: Features the Calibre 825 automatic "bumper" movement, which uses an oscillating weight that bounces between two spring sides rather than rotating 360 degrees. It operates at 18,000 vph with a power reserve of roughly 50 hours.

• Λειτουργίες: Integrated mechanical alarm and date display at 3 o'clock.

• Dual Crowns: The crown at 2 o’clock sets the alarm disc and winds the alarm; the crown at 4 o’clock sets the time and winds the movement.

• Καντράν: Silvered dial with a central revolving alarm disc and applied baton hour markers.
