Perpetuating a tradition, Master Compressor Diving Alarm Navy SEALs

Presented with a diameter of 44 mm, this timepiece reinterprets the tradition of diving watches created by Jaeger-LeCoultre in the 1950s with its famous Memovox watches, the first diving watches to be fitted with an alarm. Its black dial featuring luminescent figures and indexes affords a high degree of legibility.
