The Alpina Seastrong Diver 300 Black Chronograph Big Date


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 revealed the Seastrong Diver 300 Chronograph Big Date Collection. With the new Diver 300 Black variant, Alpina proposes an all black execution of its successful professional diving big date chronograph.


The aluminum, unidirectional, turning bezel, turns in just one direction: anti-clockwise. The 60 minutes markers on the black bezel are luminous, as are the dial indexes, which perfectly contrast against the matt black dial. The watch’s hands are luminous for maximum readability in low visibility conditions, and the minute’s hand is oversized to instantly read diving time.


Alpina Seastrong Diver 300 Black Chronograph Big Date features a 44 mm black PVD coated, cushion shaped, stainless steel case,a screw-in crown and case-back, a scratch-resistant sapphire crystal and a black water-resistant rubber strap accompanied with a black PVD coated buckle. The beautiful engraving of the Trident symbol on the case-back provides for an additional and distinctive aesthetic feature.


The Alpina Seastrong Diver 300 Black Chronograph Big Date encases the AL-372 quartz chronograph movement. This high precision and extremely reliable 1/10th of sec. Swiss quartz chronograph movement features 30 minutes and 10 hours chronograph counters, add and a split functions, a big date and provides a battery life of 48 months.
