Alpina Seastrong Diver 300 Heritage  Men's Blue Strap Quartz Watch - AL-520NS4H6

The Alpina AL-520NS4H6 Seastrong Diver 300 Heritage is a distinguished men's automatic diver's watch that marries a vintage aesthetic, inspired by a 1960s original, with robust modern engineering. Encased in a polished 42mm stainless steel case with an engraved, solid case back featuring the brand's Alps and trident logo, this timepiece boasts a substantial 300-meter water resistance rating facilitated by dual screw-down crowns. A durable, domed sapphire crystal protects the clean, symmetrical white dial, which is free of a date indicator and complemented by luminous silver hands and indices for exceptional legibility underwater or in low light. The watch incorporates a practical internal rotating bezel with a 60-minute diving scale, operated by the upper crown, a signature feature of authentic diver's instruments. Powering this reliable watch is the Swiss-made AL-520 automatic caliber, based on the Sellita SW200-1 movement, which provides hours, minutes, and seconds functions with a reliable 38-hour power reserve. The timepiece is typically secured with a blue canvas or rubber strap and is designed to perform in both demanding aquatic environments and elegant social settings.
