Seiko Prospex Automatic Speedtimer SPB513J1

Sportiness, precision, and Seiko tradition come together in the new Automatic Speedtimer models. This innovative version introduces a three-hand configuration with automatic movement for the first time, enhanced by a functional inner rotating bezel for the countdown. The design recalls the iconic flowing case of the 1972 Seiko Speedtimer model, beloved by enthusiasts and known as the “Panda” model. This stylish detail celebrates the history of Japanese manufacturing with a contemporary spirit. Perfect for those seeking a reliable instrument even in the most dynamic situations, the inner flange allows for flexible measurement of time intervals, such as the countdown to the start of a race or the timing of a pit stop. A Lumibrite-coated ▼ indicator ensures excellent readability even in the dark or in low-light conditions.
