Seiko Prospex Speedtimer Solar Chronograph is powered by Seiko’s V192 solar movement, offering precision of plus or minus 15 seconds per month and approximately six months of operation when fully charged. Designed for drivers, collectors, and everyday wearers who value timing precision, the Prospex Speedtimer line reflects Seiko’s long standing connection to sports timing with a compact chronograph format made for regular use. The chronograph measures elapsed time up to 60 minutes in one fifth second increments, while the 24 hour hand, small seconds hand, power reserve indicator, date display, and tachymeter function add useful timing and reference capability. Framed by a 39.0 mm stainless steel case, the white sandblast finished dial uses contrasting subdials, LumiBrite hands and indexes, and a clear chronograph layout for strong readability. Crafted with a stainless steel bracelet, three fold clasp with push button release, curved sapphire crystal, and inner anti reflective coating, this Speedtimer delivers 100 meters of water resistance and a balanced 45.5 mm lug to lug profile for confident daily wear.
