Alpina Seastrong Diver Automatic Extreme Blends Earth And Sea 

Alpina Seastrong Diver Automatic Extreme Blends Earth And Sea 

Alpina’s new Seastrong Diver Extreme Automatic harnesses the power of its Extreme case to grace its Seastrong collection for the first time. 

Alpine and maritime adventures are now blended together in an innovative, powerful and distinctive piece housed in a 39 x 40.50mm steel case. One variation sporting an anthracite dial features an integrated steel bracelet borrowed from the Extreme line, first unveiled in 2023. The other two sporty, dynamic alternatives come with a navy blue dial on a rubber strap in the same hue or with an orange flange and a similarly matching rubber strap. Each timepiece is a certified three-hands-and-date dive watch, water resistant to 300m. 

In an achievement akin to the successful negotiation of obstacles in outdoor sports, Alpina has completed a technical and stylistic challenge, adapting its iconic Extreme case to its Seastrong Diver line of dive watches. It’s a bold decision in the world of watchmaking, where most manufacturers prefer to keep their ranges and models strictly separate; as such it illustrates the significance of Alpina’s compact and assertive cushion format. Henceforth, the latter’s success reflects not only that of the Extreme line, but also that of the Maison as a whole. 

The result is quite simply compelling. The smaller, unisex version of the case (39 x 40.50mm) fits seamlessly into the Seastrong collection, with Earth and Sea coming together here as naturally as an ocean wave meets the coastline. While the Seastrong Diver Extreme Automatic retains a decidedly sporty style, its more restrained dimensions mean it’s ideal for more urban, everyday wear beneath a shirt or jacket, too. The piece is a further embodiment of the Alpina ethos: uncompromising, high-tech watchmaking that’s also measured, balanced and never showy, the fruit of a legacy of good taste and etiquette built up over the long history of the brand, which celebrated its 140th anniversary last year. 

The new Seastrong Diver Extreme Automatic is now available in three variations, all of them reflecting the technical and style codes that define the collection’s DNA.
