Official description

Adjusted to modern standards, the new Alpina Seastrong Diver Heritage bears a 42mm bronze color PVD stainless steel case with two screw-in crowns at 2 and 4 o’clock. The top crown has a grid-like pattern and is used to adjust the rotating inner diving bezel while the bottom crown is used to set the time and date, the watch resists water pressure up to 30 bar, corresponding to a diving depth of 300 m/1000ft.

The Alpina Seastrong Diver Heritage uses an automatic movement based on a Sellita SW 200 movement modified by Alpina and named caliber AL-525. This is a 26-jewel self-winding caliber with a 38-hour power reserve and 28,800/h frequency. Available with an elegant brown color dial it features a brown or cream color rotating inner bezel with brown or beige markers, a date window at 4 o’clock, rose gold-plated indexes and hands with white luminous treatment.
