In the world of alarm divers watches, the Vulcain Nautical Cricket is probably one of the most sought-after alongside the Jaeger Polaris. Made in far fewer numbers, Vulcain enlisted the help of three exceptional individuals, Hannes Keller, Arthur Droz und Max-Yves Brandly. Hannes Keller was the most famous of all due to his diving exploits as he set a world diving record in 1962 at 300m. Max-Yves Brandly was an explorer and film director. The last of the three was the Swiss Arthur Droz, instructeur national de plongée et délégué du Centre d’investigations et d’activités sous-marines. According to the consignor, he bought the watch from his wife directly and it participated in the first tests. Kept in overall remarkable condition, a truly great example of one the rarest alarm dive watches ever produced.
