1966 Seiko Mono Pusher Chronograph (Ref. 5717-8990)

Designed alongside the Seiko World Time, both were created to celebrate and assist in the 1964 summer Olympics that would be hosted in Japan, also known as the 'Games of the XVIII Olympiad'. This specific chronograph hosts a 60-second timer and the pusher can be used to start, stop, and reset the chronograph feature. The ref. 5717-8990 also features a date wheel, which was not present in the first 45899 Mono Pusher model.
