The Cricket Nautical was the fruit of research conducted by 3 experts who pooled their knowledge and experience and, together with Manufacture Vulcain, developed the very first diver's watch that would not only feature a system for determining no-stop dive times built right into the dial, but also sound a real alarm to signal the diver “time to get back to the surface!” – in a sleek package water-resistant to a depth of 300 meters. The trio of passionate divers: Hannes Keller, a talented Swiss physicist/ mathematician, occasional pianist, and deep-sea diving pioneer; Max-Yves Brandily, explorer and filmmaker; and Arthur Droz, a national certified diving instructor and representative of the C.I.A.S (Centre d'Investigations et d'Activités Sous-Marines – Center for Underwater Investigations and Activities).

Here, Vulcain would like to pay tribute to Hannes Keller, who passed away last year, on 25 December 2022. On November 3, 1966, in Toulon, France, he reached the abyssal depth of almost 250 meters with a Cricket Nautical on his wrist. The record was witnessed and validated by none other than Jacques Cousteau, already a legend by then.
