The new SRQ039J1 automatic chronograph pays tribute to the design of the 1964 chronometer. Its dial is faithful to the 1964 1/5th of a second time counter and incorporates every detail of its design, providing the precision and readability that were essential to the original's superior performance. The long, concave push-buttons ensure great handling, which made the original time counter famous. The watch incorporates a new movement from the 8R series, Seiko's most advanced chronograph, calibre 8R46. It shares the same performance attributes as the Calibre 8R48 but incorporates two sub-dials instead of three and has a date display at six o'clock.
