SEIKO PROSPEX SPB121 (Alpinist)

The SEIKO PROSPEX SPB121, known as the Alpinist, is a legendary timepiece designed for adventurers and outdoor enthusiasts. Originally introduced in 1959 as Seiko’s first sport watch, the Alpinist series has evolved while maintaining its rugged elegance and functional design. This modern reinterpretation features a green sunray-finish dial with gold accents, a rotating inner compass bezel, and LumiBrite hands and markers for enhanced visibility.

With a stainless steel case, brown leather strap, and sapphire crystal with anti-reflective coating, this watch blends classic aesthetics with modern durability. The screwdown crown and see-through caseback ensure both water resistance and a glimpse into the automatic movement inside.
