There is a tachymeter scale around the dial. Another special feature is the 6 o'clock sub-dial that doubles as an elapsed time counter and seconds display. What looks like a 12 o'clock date window is actually a golf stroke or point counter, operated with two buttons on the left side of the case. Seiko unveiled another version of the movement, the 6.4mm thick caliber 5718, on a limited edition steel watch that is very rare and longing for collectors today. Seiko has corrected this by replacing the fragile bezel with a sturdy steel bezel.

The problem with this first chronograph series is that the bezel tended to break. After stopping the chronograph at the end of the interval, the elapsed time was read using a rotating bezel and the elapsed time was read using a regular dial. To measure intervals longer than 1 minute, the user activates the chronograph and rotates the bezel until the tip of the large triangle is exactly opposite the tip of the minute hand. Since the Seiko chronograph watch did not have an elapsed time counter, Seiko was equipped with a rotating bezel calibrated in 1 minute increments. The case was made of steel and had a diameter of 38.2 mm and a thickness of 11.2 mm. When the chronograph mechanism is turned on, the movement operates for 38 hours. The balance was adjusted to 5.5 Hz, or 39,600 vph. Prominent features of this 6.1 mm thickness movement are one button that triggers the function of the chronograph, horizontal coupling, start, stop and zero return functions. Equipped with a 12-rigged hand-wound caliber 5719. Suwa Seikosha, the factory of SEIKO in Suwa, has developed a watch that was released in time for the 1964 Summer Olympics. When Seiko started designing Japan's first watch chronograph, its goal was to produce a watch that was as status symbol as a timing device.
