The Alpina Seastrong Diver 300 Black Chronograph Big Date

With the Seastrong collection, Alpina Watches has made diving watch history since the 1960s when the Seastrong 10 was already capable of reaching depths of 200m/660ft. In 2015, Alpina revealed the Seastrong Diver 300 Chronograph Big Date Collection and today, with the introduction of the new Diver 300 Black variant, Alpina proposes an all-black execution of its successful professional diving big date chronograph – a highly recognisable diving watch due to its all black color code and its oversized red minute hand. This model is designed to cope with the most extreme conditions any professional diver could ever encounter, starting with water resistance to no less than 300m/100ft.
