Official description

There are evolutions and ruptures. The new Seastrong Diver Extreme Automatic belongs to the second category. For the first time, Alpina has extracted the power of its cushion-shaped Extreme case and implemented it within its Seastrong collection. Alpine conquest and the sea merge to create a powerful, racy self-winding original in a 39 x 40.40 mm steel case. A first variation with an anthracite dial is fitted with the integrated steel bracelet of the Extreme line, unveiled in 2023. The other two versions, both sporty and dynamic, feature a navy blue dial on a matching rubber strap, or an orange flange and matching rubber strap. Each model, a certified diver's watch with three hands and date, is water-resistant to 300 metres.

Alpina has taken an aesthetic and technical step forward in its outdoor activities: the company has chosen to adapt its iconic Extreme case to its Seastrong Diver line of diving watches. This choice, rare in a watchmaking industry that prefers to compartmentalise its ranges and models, reflects the importance of this compact and responsive cushion-shaped case. Its success is no longer just that of the Extreme line, but that of the entire Alpina brand.

The result is obvious. In its reduced, unisex version measuring 39 x 40.40 mm, the case is a spontaneous addition to the Seastrong collection. Land and sea come together intuitively, just as the shoreline of an ocean naturally embraces the coastline that welcomes it. The Seastrong Diver Extreme Automatic has a sporty aesthetic, but its measured size means it can easily be adapted to everyday urban life, under a shirt or jacket. Here Alpina confirms its approach to technical watchmaking, uncompromising but fair and balanced, never ostentatious - a heritage of good taste and decorum stemming from its long history, which last year passed the 140th anniversary mark.

The new Seastrong Diver Extreme Automatic is now available in three variations. They share the same aesthetic and technical vocabulary, the DNA of the collection.
