The Seastrong Diver by Alpina is a true testament to Swiss ingenuity, combining style and functionality for diving and water sports enthusiasts. Built around a cushion-shaped 316L stainless steel case with brushed and polished finishes that subtly catch the light, it exudes robust elegance. A diameter of 39 mm and thickness of 12 mm ensure comfortable wrist presence without sacrificing durability. The unidirectional ceramic bezel with luminescent markers provides reliable time-tracking during underwater exploration.
The dial is a statement in itself, with its black sandblasted finish lending a sophisticated, professional edge. Hands and indices coated with SuperLuminova C1 illuminate hours, minutes, and seconds with sharp clarity even in the darkest conditions. Arabic numerals on the bezel make dive time calculations effortless. A date window at 6 o'clock adds functionality and precision. Protected by an anti-reflective sapphire crystal, the dial retains its legibility and brilliance in any lighting.
Powering this timepiece is a Swiss automatic movement based on caliber AL-525, derived from the legendary Sellita SW200. This precision mechanism beats at a frequency of 28,800 A/h, delivering smooth hand motion and a power reserve of 38 hours. A convenient date function is displayed via a window on the dial.
The black rubber strap on this watch is as comfortable as it is built to last. With a 21 mm lug width and a deployant clasp for easy fastening, it delivers a secure fit even during the most intense water activities. The resilience of the rubber ensures the strap retains its shape and texture despite constant exposure to saltwater and humidity.
Built for underwater adventurers, this watch delivers an impressive water resistance of 30 ATM, allowing safe diving to 300 meters - giving you the freedom to explore the ocean's depths. A screwed crown reinforces this protection by preventing any water from reaching the movement, making this timepiece a dependable partner for every aquatic pursuit.
