The Alpina Seastrong Diver Heritage Watch is based on the Alpina 10 from 1967. The Alpina 10 was a super compressor divers watch and these days it is pretty rare and hard to come by. The Seastrong Diver Heritage Watch recalls the original with its rotating ring and two crowns.

Firstly, the crown at 2 o’clock enables the rotating ring to be easily adjusted. This diving feature is also useful in everyday life. For example, the arrow can be positioned so that the approaching hour hand indicates when parking time is running out. Secondly, the dial is also pretty special. In two tone silver and black, it looks really smart. The applied silver indexes also give the dial a premium look. Along with the hands, they are have a luminous coating so that they shine brightly in the dark. Thirdly, the case has a brushed finish with a narrow, polished bevel running along the side.

The black strap is durable in rubber with a stamped “tread” pattern and functional pin buckle. Water resistant to 30 bars (300m), the Alpina Seastrong Diver Heritage Watch is suitable for scuba diving. It also has an engraved screw caseback. Finally, a scratch-resistant sapphire crystal completes the look.
