In 1967 Alpina produced a Super Compressor cased diver called the Alpina 10. This was one of many Super Compressor divers made during that era, and the Alpina 10 is a rare and desirable model for collectors these days. Just 50 years later, the highly regarded diving watch is back in the Alpina Collection, this time as the "Seastrong Diver Heritage". Its illustrious predecessor from the 1960s is recalled in two operating elements in the right case flank and the rotating ring which was (at that time, for good reason) shifted into the inside of the case.

Alpina Seastrong Diver heritage with sunburst dial

With the help of the crown, the rotating ring can be quickly and easily adjusted at "2". The 60 minute division is also useful for non divers. For example, the arrow can be positioned so that the approaching hour hand indicates when parking time is running out.

The dial of the Seastrong Diver Heritage Ref. AL-525G4H6 is a work of art. And has to be admired in person to understand the beauty and work that has been put into it. The sunburst sunray dial, depending on the lighting goes from a deep grey to a deep blue; due to the sunburst finishing. The applied hour markers give the watch a more premium look.

Hand satin brushed case with delicate polished lines

Thanks to the modern case design, the classic stainless steel case (now increased to a diameter of 42 millimetres) with its engraved screwed case back resists water pressure up to 30 bar, corresponding to a diving depth of 300 m/1000ft. Like most Alpina watch cases and not commonly seen for watches in this price range, it's case is hand satin-brushed on all surfaces, except for a intricate, narrow bevel that runs along its length. The Alpina's case finishing rates highly for watches costing even 2-3 times more. 

Internal rotating bezel with SuperLuminova

The modern AL-525 automatic calibre ensures timekeeping. This is the equally reliable, robust and accurate SW 200 from Sellita. Alpina has refined it with its customary attention to detail, giving the ball bearing mounted rotor the asymmetric form signature to the brand. The balance wheel completes 28,800 vibrations per hour. Fully wound, it has 38 hours of power reserve.
