The Seiko Prospex Speedtimer watch is a reimagined version of the 1969 Seiko Speedtimer, originally the world's first automatic chronograph watch with a column wheel and vertical clutch. This timepiece is inspired by the design of the 1964 stopwatch. It features a solar-powered three-hand movement and a new automatic 8R series chronograph movement. The dial and hands are treated with Lumibrite for extra visibility at night. With its crown and push buttons, this reliable professional piece is perfect for everyday wear. This collection is inspired by Seiko’s professional timekeeping heritage and the flowing lines of the 1969 world’s first automatic chronograph watch. The watch charges from both natural and electric light, a practical and reliable design for extreme or everyday environments. The 39 x 13mm stainless steel case features a tachymeter bezel, a white dial with blue subdials, and luminous hands and hour markers. It is finished with a stainless steel bracelet with a three-fold push-button clasp and is 100m water resistant.
