Built for the world of off-road motorsport Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. This new three-hand Speedtimer Mechanical is powered by Seiko's own 6R55 automatic movement. Unique to this reference is a crown at 4:00, which operates an inner rotating countdown bezel, used to measure key intervals in motorsports competitions, such as the time remaining before the start and target durations for tasks such as tire changes and refueling. Inspired by the color of rally cars, which minimizes light reflection, the cream colored dial is finished with sporty orange accents to enhance legibility.
