Jaeger-LeCoultre Master Compressor W-Alarm Mens Watch Q1778470 Watch Details

Despite the massive case, the alarm buzz is clear and easily audible, quite a feat given its large size. JLC achieves this by running the gong around the circumference of the movement, instead of attaching it to the caseback as in earlier Memovox alarm watches. This layout is more akin to a minute repeater than an alarm watch. Even when the alarm is at full wind, it can be deactivated simply by depressing the push piece around the 10 o'clock city crown. The acoustics within the case have been optimized to ensure a powerful and harmonious tone with consistently identical intensity and tone, whether the alarm watch is being worn or not.

Local hour and minute hands, trapeze-shaped gold-plated, openworked, luminescent.

Crown at 2 controls the alarm function and rapid date correction in counter clockwise direction. Crown at 4 starts the watch, adjusts time; crown equipped with a compression key. Crown at 10 to display world time, Double-sided push-piece at 10 to start/stop the alarm.


Since 1833, when the inventive Charles Antoine LeCoultre established this venerable watchmaker, it has produced some of the most outstanding and innovative timepieces. It wasn't until 1931, however, that the Jaeger-LeCoultre brand rose to international fame. It was then that the Reverso - an ingenious reversible watch - was unveiled to the public.
