Seiko Prospex Speedtimer watch, black steel, SFJ007P1
Black Seiko Prospex Speedtimer watch with solar movement and 1/100-second chronograph
This Speedtimer measures time to an accuracy of 1/100 of a second. There are three small timing subdials at the top and sides of the dial, and the time display sits at the bottom in its own subdial. The dial surface is designed to resemble the texture of a running track, and the gold-coloured hands refer to a gold medal. A curved sapphire crystal protects the dial, and the LumiBrite coating keeps the time legible in the dark.
The solar-powered 8A50 movement lasts up to 6 months when fully charged. Seiko is the main sponsor of World Athletics and the official timekeeper of the World Championships, and this limited run of 4,000 pieces celebrates the 2023 Budapest championships. The watch has a black steel case that is 42 mm wide, weighs 152 g and is water-resistant to 100 m / 10 atm: it is suitable for swimming and snorkeling, but not for scuba diving.
