Not present in any literature or advertising and produced only during 3 years from 1959 to 1962 in 1061 pieces (even less than the later Polaris made in 1714 examples), it was marketed as not only the first diving wristwatch by Jaeger Lecoultre but also as the first diving watch with mechanical alarm. While the US edition (featuring a different dial configuration with baton indexes) and only signed LeCoultre, this particular Deep Sea Alarm is the much rarer European version signed Jaeger LeCoultre featuring triangular indexes and made in only about 200 examples overall. Recently discovered in an abandoned convenience store in France, the example has been left in as found condition featuring a beautiful tropical brown dial.
