Overview
Alpina Seastrong Diver Extreme Automatic Watch with Blue Dial.
The Seastrong collection brings together Alpina’s dive watches, each with a ceramic bezel and luminescent hands. The Seastrong Diver Extreme Automatic introduces the Extreme cushion case to the Seastrong collection for the first time. In stainless steel, it measures 39 mm, is 40.5 mm long, and is 12.65 mm thick, with a unidirectional notched ceramic bezel.
The AL-525 automatic caliber powers the hours, minutes, seconds, and date at 6 o’clock beneath an anti-reflective sapphire crystal.
The navy blue dial evokes the depth of the ocean, with Alpina’s triangle pattern inside a matching outer ring. The silver indexes and the hands have white luminescent treatment. An integrated navy blue rubber strap measures 16 mm at the lugs and fastens with a push-button folding clasp.

Questions & Answers
What is the Seastrong collection built for?
It is designed for diving. Seastrong brings together Alpina’s dive watches, with ceramic diving bezels and luminescent hands. Gottlieb Hauser founded Alpina in 1883, and Alpina produces and assembles its movements and watches at its manufacture in Plan-les-Ouates, Geneva.
How do you time a dive with the bezel?
At the start of the dive, align the zero of the bezel with the minute hand. The minute hand then reads the elapsed minutes off the scale, and because the bezel turns only counterclockwise a knock can only shorten the dive time it shows.
How long will the watch run when not worn?
About 38 hours when fully wound. Daily wear keeps the mainspring wound. If the watch stops after a longer period without wear, a few turns of the crown will restart it.
Who makes the movement?
Alpina builds the AL-525 on a Swiss Sellita SW200 automatic base, and assembles its watches at its manufacture in Plan-les-Ouates, Geneva, as part of the Frederique Constant group.
How resistant is the crystal to scratches?
Sapphire ranks 9 on the Mohs scale, just below diamond, so few materials encountered in everyday wear will scratch it, and the anti-reflective treatment keeps the dial readable at an angle in bright light.
