SEIKO 5 SPORTS SPEED-TIMER 7017-8010S Pulse Meter

This is the **SEIKO 5 SPORTS SPEEDTIMER**, a representative vintage chronograph from Seiko.

This is a highly distinctive model featuring a unique pulse meter scale on the dial.
The deep blue dial, white indices, and vibrant orange chronograph second hand give this watch a sporty and bold design that is characteristic of Seiko watches from the early 1970s. This particular pulsometer version is known as a rare dial variation that differs from the usual tachymeter version, making it a highly sought-after item among vintage Seiko collectors.

Furthermore, it features a rare original bracelet, making the bracelet alone extremely valuable.


■ A special movement called 7017

It is equipped with the Cal.7017 automatic chronograph movement.
The 7017 is a Seiko-exclusive 70-series chronograph movement that appeared around 1970, characterized by its slim design with a thickness of only about 5.9mm. Furthermore, it is equipped with a flyback mechanism that allows the chronograph to be reset while in operation, making it more than just a design watch, but a timepiece that showcases the technical prowess that Seiko poured into mechanical chronographs at the time.

While it's a sports watch, it's not just an "old chronograph"; it's a timepiece that embodies the design and mechanical technology characteristic of Seiko in the early 1970s.
