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, Swiss watch brand Alpina revealed the Seastrong Diver 300 Chronograph Big Date Collection. This year the traditional watch maker proposes an all black execution of its successful professional diving big date chronograph.

Dressed in all black and its equipped with an oversized red minute hand, the Alpina Seastrong Diver 300 Chronograph Big Date is a professional diving watch with water resistance up to 300m/100ft. The aluminum, unidirectional, turning bezel, turns in just one direction: anti-clockwise. In addition, 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.

Built-in features that are relevant to the professional diver include a 44 mm black PVD coated, cushion shaped, stainless steel case, screw-in crown and case-back, a scratch-resistant sapphire crystal and a black water-resistant rubber strap. The beautiful engraving of the Alpina diving 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 30minutes and 10 hours chronograph counters, add and a split functions, a big date and provides a battery life of 48 months.
