The Seiko Prospex Speedtimer SSC911P1 brings modern solar technology to a classic, 1969-inspired racing design. Featuring a highly legible "Panda" style silver sunray dial with contrasting black subdials, this 41.4mm "Go Large" chronograph commands a sporty presence on the wrist. Powered by the advanced Caliber V192 solar movement, it charges from any ambient light source and never requires a battery replacement.
