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 GMT takes the same unique stepped 39mm square case and impressive 300m of water resistance of the Seastrong Diver Extreme and adds in a globetrotting GMT complication.. Due to the lug-to-lug being so close to the case width, the watch 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 GMT is available in black and white dial variations — each featuring bold triangular serrations — and are paired with a black rubber strap.

Powering the Seastrong Diver Extreme GMT is the Swiss-made Alpina AL-560, a Sellita SW330-derived caliber. An automatic movement, it features 25 jewels, hacking, hand winding, date, a caller GMT complication (independent 24 hr hand), a frequency of 28,800 beats per hour, and a power reserve of at least 50 hours.
