Seiko Men's Prospex Alpinist "Night Vision" Alpinist Limited Edition Watch SPB337

The Seiko Prospex SPB337 “Night Vision” Alpinist Limited Edition is a stealth-inspired reinterpretation of Seiko’s legendary explorer’s watch, combining rugged outdoor functionality with a bold all-black aesthetic. Part of Seiko’s 2023 Black Series collection and limited to 5,500 pieces worldwide, the SPB337 features a black hard-coated stainless steel case and bracelet paired with a textured black dial designed to minimize reflection and maximize legibility in low-light conditions. Signature cathedral hands, Arabic numerals, and the rotating inner compass bezel preserve the classic Alpinist identity, while vivid green LumiBrite Pro accents create a striking “night vision” effect inspired by nighttime exploration and diving missions. Powered by Seiko’s automatic Caliber 6R35 movement with a 70-hour power reserve, the watch also offers 200 meters of water resistance, a screw-down crown, sapphire crystal, and exhibition caseback for modern reliability and versatility. With its compact 39.5mm case and adventurous spirit, the SPB337 delivers a unique blend of heritage design, contemporary styling, and tool-watch capability.
