Designed for those who live every moment as an adventure, the Seiko® Prospex Speedtimer Solar Chronograph pays tribute to the iconic 1969 Speedtimer, the world’s first self-winding chronograph. Inspired by a model nicknamed after a famous astronaut, this watch combines bold design with modern solar technology. The vibrant yellow dial with contrasting subdials is framed by a two-tone red and blue aluminum tachymeter bezel, and the solar-powered movement provides a 6-month power reserve when fully charged. Built for precision and durability, it features a stainless steel case with anti-reflective coating on the inner surface and a power reserve indicator for added confidence. Dimensions: Case diameter: 41.4 mm. Case thickness: 13.0 mm. Lug-to-lug: 45.9 mm.
