1972 leCoultre Memovox HPG (High Precision Garanteed) automatic alarm ref. E3072.
The Memovox was first introduced by Jaeger-LeCoultre in 1950/51. The two separate crowns allowed you to manually wind and set the alarm and timekeeping parts of the movement separately.
Symbolizing the planned efficiency of the post-war boom period, the Memovox literally meaning voice of memory quickly became the watch of excellence for men-about-town. Its striking mechanism gave a pleasant accent to the schedule of daily life: waking up, appointments, train timetables or parking meters.
Founded by Antoine LeCoultre in 1833, the brand has hundreds of inventions, over a thousand calibers to its name and some of the most important watches made in the 20 century, incliuding the Memovox, Reverso and Atmos. The company has been a fully owned subsidiary of the Swiss luxury group Richemont since 2000.
