Product Description

Precision, durability, and classic diving heritage—the Alpina Seastrong AL-525LBN4V6B Automatic Dive Watch is built for performance in extreme conditions while maintaining a refined, everyday elegance.

This professional-grade diver features a 44mm stainless steel case, a black dial, and a unidirectional stainless steel bezel—all protected by a scratch-resistant sapphire crystal. The stainless steel bracelet is secured with a deployment clasp, offering both comfort and reliability in high-pressure environments.

Powered by the Alpina Caliber AL-525 automatic movement with 26 jewels and 28,800 vibrations per hour, this watch delivers precision timing and robust mechanical performance. A transparent case back reveals the movement in action, highlighting its fine Swiss craftsmanship.

With a water resistance of 300 meters (1000 feet), the Seastrong is ideal for recreational diving, snorkeling, sailing, and other aquatic adventures. A date display is positioned at 3 o’clock for added functionality.
