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).
