About the Alpina Seastrong Collection


From crafting chronometers for the German Navy during the second world war to defining the art of making sports watches, Alpina has stood the test of time. But in the 1960s, Alpina set off a chain reaction of professional diver’s watches that would start dominating the ever-evolving horological world. Dubbed the ‘10 Seastrong’, the 1969 version of the diver’s watch had two crowns, one for decompression and the other for adjusting the time. Now, the Alpina Seastrong collection carries the legacy left by the 10 Seastrong.


Perfecting the characteristics of a diving watch, the Alpina Seastrong collection is equipped with a triangular index marker at 12 o’clock. Whereas, within the Seastrong Diver 300 and Seastrong Diver Gyre series, the date window is fixed at the 3 o’clock marker with luminescent index markers and a unidirectional rotating bezel. What glamourises the collection is the Seastrong Diver 300 Heritage series. Taking its cues from the original Seastrong, the Heritage series is equipped with two crowns with a vintage-inspired dial. What makes the Alpina Seastrong a typical diver’s watch is the addition of the unidirectional rotating bezel. A unidirectional rotating bezel is used in measuring the time taken for a particular dive. Whereas, the water-resistant capacity of 300m offers the capability of exploring deep seas with ease.


Alpina has collectively revamped its diver’s collection with brightly coloured hues and well-illuminated hands. The design of the Seastrong collection perfectly encapsulates the modern diving watches. Whereas, with the Diver 300 Heritage series, Alpina retains the design elements of the original 10 Seastrong with two crowns and a polished bezel.
