Seiko Prospex Speedtimer watch, steel, black, SFJ003P1
Stainless Steel Seiko Prospex Speedtimer Watch with Black Dial and Three Subdials
There are four pushers on the sides of the case, and their functions are printed around the edge of the dial: Reset/Split, Start/Stop, Mode and Adjust. The black dial has three subdials and a time display at the bottom. The case and bracelet are stainless steel, the case is 42 mm wide and the watch weighs 152 g.
The solar movement measures time to an accuracy of 1/100 of a second, and when fully charged it has a power reserve of up to 6 months. A curved sapphire crystal protects the dial, and the LumiBrite coating keeps the hands and indexes legible in the dark. Water resistance of 100 m / 10 atm is enough for swimming and snorkeling, but not for scuba diving. Prospex is Seiko's collection of sports and diving watches, and the Speedtimer name comes from the 1969 automatic chronograph.
