In 1969, the first Alpina 10 Super Compressor dive watch was introduced with two crowns, one for controlling the inner rotating bezel, which can be timed by a 1-60 minute scale. The "Seastrong" watch is water resistant to 200 meters, diamagnetic and comes with a unique super compressor case. To pay tribute to this long-established watch collection, Alpina launched the "Seastrong Diver Heritage" in 2016.

The new Alpina Seastrong Diver Heritage watch features a 42mm diameter bronze PVD stainless steel case with two screw-in crowns at 2 o'clock and 4 o'clock to meet modern standards.
