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.
