Alpina Seastrong Extreme 40mm AL-525B3VE6

The Alpina Seastrong Diver Extreme Automatic REF AL-525B3VE6 is a powerful expression of Swiss watchmaking heritage, engineered for men who demand precision, resilience, and timeless design.

Crafted in Switzerland to the highest standards of quality, this professional men’s dive watch features a robust 39 x 40.5mm brushed and polished stainless steel case, combining strength with refined finishing. Topped with a unidirectional matte black ceramic diving bezel, it delivers both technical performance and bold, masculine style. Designed in the pure tradition of classic diving watches, the timeless black dial is enhanced by silver-tone hands and hour markers filled with “old radium” luminous treatment, ensuring exceptional legibility in low-light and underwater conditions.

Powered by the reliable Swiss-made Alpina AL-525 automatic movement, this luxury sports watch offers hours, minutes, seconds, and a discreet date display at 6 o’clock, along with a 38-hour power reserve. Protected by anti-reflective sapphire crystal, the dial remains clear and highly readable in all environments. Built for serious adventure, the screw-down case back engraved with the Seastrong emblem reinforces its durability and water resistance up to an impressive 300 metres, making it a true professional diving watch. The textured black rubber strap provides superior comfort and flexibility, secured with a push-button folding clasp for dependable wear whether at sea or on land.

What we love about the Alpina Seastrong Diver Extreme Automatic REF AL-525B3VE6 is how it stays true to Alpina’s century-long Swiss heritage while delivering modern performance and uncompromising build quality. Its combination of ceramic, steel, and precision automatic engineering creates a confident, masculine dive watch that feels equally at home beneath the waves or worn as a bold everyday statement of Swiss craftsmanship.
