Seiko - 1960s Monopusher Chronograph

WHAT WE LOVE:

The Seiko Monopusher Chronograph 5717-8990 is a legendary chronograph that embodies the pioneering spirit of Seiko’s watchmaking in the 1960s. Released in 1964 as part of Seiko’s first-ever chronograph series, this single-pusher stopwatch-style timepiece was developed for the Tokyo Olympics, marking a significant milestone in both the brand’s history and the evolution of wrist chronographs.

Housed in a 38mm stainless steel case, the 5717-8990 features a clean, mid-century aesthetic with a polished bezel and finely brushed lugs. The silver sunburst dial exudes timeless elegance, complemented by applied baton indices and slim dauphine hands. A central chronograph seconds hand and a date window at 3 o’clock add to its functionality while maintaining a well-balanced and uncluttered look.

WHAT'S INSIDE:

Unlike modern chronographs, this model is operated by a single pusher at 2 o’clock, which starts, stops, and resets the chronograph function in a single motion. This mechanism is powered by the Seiko Caliber 5717, a manual-winding, column-wheel chronograph movement, renowned for its smooth operation and reliability.
