With the SEASTRONG collection, Alpina Watches has made diving watch history since the 1960’s when the Seastrong”10″ was already capable of reaching depths of 200m/660ft. In 2015 Alpina shows the Seastrong Diver 300 Chronograph Big Date. An extremely well readable expert diving chronograph range that is 300m/1000ft water-resistant, instantly recognizable as a result of its distinctive coloured unidirectional turning diving bezels and its own oversize minute hand for optimum diving time readability. Everything about this model is intended to cope with the most extreme conditions any expert diver could ever encounter, starting with water resistance to no less than 300 meters. That’s 1,000 feet below sea level, so the watch can go to depths no human ever could. With this”fail-safe” attribute the number of elapsed minutes cannot be accidentally decreased, only improved. Additionally, the 60 minutes mark on the bezel are luminous, as are the dial indexes, which absolutely contrast against the matt black dial. The watch’s hands are glowing for maximum readability in low visibility conditions, and the second’s hand is oversize to safely read diving time.
