The Watch

This Seiko Mono-pusher Chronograph Ref. 5717-8990, was first produced in 1964 for the 18th Tokyo Olympics. Suwa Seikosha developed their first chronograph wristwatch as a status symbol as well as a timing device. They are affectionately known as the “Seiko Chronostop” as it looks very similar to the Omega Chronostop. Seiko was the official timekeeper of those games. Its 38mm round stainless steel case has brushed and polished surfaces. On the right side a single pusher at 2 o’clock and a large crown, making adjustments a breeze. The stainless steel bi-directional bezel has a 60-minute scale etched into it. A domed crystal sits above a sunburst silver dial. An outer minute track is clearly printed. Applied baton indexes have chamfered edges that catch the light as you turn your wrist at 3 o’clock a date window. Thin steel hands hit their mark perfectly. Delicate tapered steel hands hit their mark perfectly. On the reverse, a screw-down case back with the Seiko Seahorse engraved in the center. Underneath the serial number, that includes the month and year of production. Inside a Manually Wound Seiko Cal. 5717, 21 jewels, 18,000 beats per hour with horizontal coupling and a column wheel to control the single pusher that does all three functions start, stop and reset to zero. Fitted on a period-correct 18mm stainless steel polished and brushed bracelet with folding clasp.
