Alpina has carved out an identity as an independent-thinking trailblazer for over 140 years. One of the earliest producers of Swiss sports watches, Alpina’s Seastrong collection of dive watches are purpose built for the deep, effortlessly blending Alpina’s heritage with a modern design philosophy.
The Seastrong Diver Extreme features a unique stepped 39mm square case with an impressive 300m of water resistance. Due to the lug-to-lug being so close to the case width, the Diver Extreme wears well on nearly any wrist. Each of its three dial variations features bold triangular serrations, resulting in a dial texture unique to the model. The Seastrong Diver Extreme is available in black, blue, and orange dials and is paired with either a semi-integrated stainless steel bracelet or strap depending on the dial.
Powering the Seastrong Diver Extreme is the Swiss-made Alpina AL-525, a Sellita SW200-derived caliber. An automatic movement, it features 26 jewels, hacking, hand winding, date, a frequency of 28,800 beats per hour, and a power reserve of at least 38 hours.

Founded in 1883 by Gottlieb Hauser, Alpina is a Swiss watchmaking house based in Geneva that has emerged as a pioneer in the world of sport, characterized by a spirit of adventure and innovation. In 1938, the brand invented the concept of the sports watch with its Alpina 4: impact-resistant, non-magnetic, water-resistant, and made of stainless steel. Since its origins, Alpina’s mission has been to design luxury sports watches delivering exceptional accuracy and reliability in extreme environments. Today, this commitment is upheld with four collections: Alpiner (Earth), Seastrong (Sea), Startimer (Air) and Heritage (paying tribute to the brand’s legacy). Alpina has built up robust partnerships reflecting its enduring commitment to the mountain environment – a constant source of inspiration – as well as a team of athletes and other friends of the brand. They are united by a common ambition: scaling new heights in the most challenging conditions.
