Seiko Prospex Speedtimer Solar wristwatch, steel, blue, SSC913P1
Steel Seiko Prospex Speedtimer Solar watch with blue dial, blue and red bezel and timing functions
The blue and red tachymeter bezel and the red seconds hand give this Seiko Prospex Speedtimer chronograph a sporty look with its blue dial. The dial has three black subdials, a date display, a 24-hour display and a charge level indicator. Sapphire crystal protects the dial, and the watch has luminous hands and indexes.
The Solar movement charges from light, so no battery replacement is needed. On a full charge, the power reserve is 6 months. The round steel case is 41 mm wide and 13 mm thick, and the steel bracelet fits wrist circumferences of 150–200 mm. Water resistance of 100 m / 10 atm withstands swimming, water sports and snorkeling, but the watch is not intended for scuba diving. The roots of the Speedtimer lie in Seiko's 1969 automatic chronograph.
