Official description

If you don’t have a blue lagoon right outside your front door, fear not: Alpina’s new Seastrong Diver Extreme Automatic GMT will whisk you away to one. Fitted with the ultra-robust case from Alpina’s outdoor Extreme line for the first time, the timepiece also features a GMT function, making it ready to travel anywhere. Two automatic models displaying the date thus join the Seastrong collection, both housed in a steel case with a ceramic bezel on a black rubber strap. The first comes with a silver dial while the second sports a black dial. The 39x40.50mm cushion format is both strong and compact, making it perfect for water sports and urban settings alike.

The new Seastrong Diver Extreme Automatic GMT really does deliver the best of both worlds. On the one hand, there’s the original DNA of a certified dive watch equipped with a screw-down caseback (making it water-resistant to 300 metres), a screw-down crown with grip, luminous hands and hour markers, and a notched bidirectional bezel.

All this is now accompanied by Alpina’s flagship design, the Extreme case. Compact, assertive and a veteran of all forms of outdoor pursuits, the case has been integrated into the Seastrong Diver GMT line for the first time. It’s a natural and obvious move: how could a case designed for outdoor adventures not encounter the dive watch that spans every ocean on the planet?
