Pre-Owned Jaeger LeCoultre Memovox Tribute To Deep Sea Alarm 40980055/AS08355

In 1947, Vulcain altered horology by creating the world's first ever wrist alarm, the Cricket.  Its success would lead to a bevy of wrist-mounted alarm watches from numerous brands.  

Jaeger-LeCoultre was one of those brands, but their approach to the wrist alarm perfected the concept and their offering, the Memovox, released in 1950, formed a new benchmark for the class. Like the Cricket, the Memovox employed a twin-crown system (the top crown to wind and set the alarm, the bottom to wind and set the time), but was differentiated by a unique alarm mechanism: a hammer that struck a post welded directly to the case back, unlike the Cricket, which uses a resonant dual case back design. With this innovation, JLC set itself apart, and created one of the most iconic models of post-war watchmaking. 

JLC quickly realized that their design was ripe for adaptation and began exploring different applications. In 1959, JLC released the Deep Sea Alarm which made waves as the first automatic wrist alarm designed to be worn under water. Rated to a depth of 200 meters, the Deep Sea Alarm was unmatched by any other manufacturer until Vulcain released the Cricket Nautical in 1961. 

Following the Deep Sea Alarm, JLC released the Polaris in 1968. Like the Deep Sea Alarm, the Polaris was a wrist alarm, but it was housed in a three-layered compressor case similar to those manufactured by EPSA. The Polaris had two case backs — one with holes bored in it to provide better acoustics for the alarm, and another inside it that formed a watertight seal. Inside of that was an additional inner layer of bronze, to magnify the sound of the alarm.

The particular watch we have here, a Tribute to Deep Sea Alarm from circa the 2010s, honors these glorious JLC alarm watches of yore — and looking at it, you’d be hard pressed to tell that it doesn’t date from the 1960s! Housed in a 40.5mm stainless steel case with a plexiglass crystal, an alarm winding and setting crown at 2:00, a time-setting crown at 4:00, and a fixed 12-hour bezel with luminous quadrants, it features a multi-tone black and silver dial with a matching ‘syringe’ handset with vintage-colored, and an inner rotating alarm indicator (as operated by the 2:00 crown. As this is a tribute to the American-market version of the original Deep Sea Alarm, its dial is signed only ‘LeCoultre,’ rather than ‘Jaeger-LeCoultre.’

Powered by the automatic Jaeger-Lecoultre Calibre 956 with 45 hours of power reserve, it comes paired to its correct black Tropic-style rubber strap with a steel pin buckle.

Water resistant to 100m and including a fully functional alarm optimized for underwater use, the Tribute to Deep Sea Memovox is a perfectly wonderful dive watch option. However, JLC made it so beautifully that we’d argue it’s equally suited to topside adventures. 

The choice is yours!
