Seiko Prospex SSC957P1 — Speedtimer Datsun 240Z Limited Edition Solar Chronograph

The Seiko Prospex SSC957P1 is one of only 4,000 pieces produced worldwide — a limited edition solar chronograph that unites two of Japan's most celebrated performance legacies: the Seiko Speedtimer and the Datsun 240Z. The Speedtimer was first introduced in 1969 as a major milestone in Seiko's watchmaking heritage. In the same year, Nissan Motor Corporation launched the Datsun — Japan's leading sports car brand. And in 1971, the Datsun 240Z, also known as the Fairlady Z and adorned with Seiko logo sponsorship, won the East African Safari Rally — one of the world's toughest races. The SSC957P1 commemorates that shared history of Japanese performance, precision, and resilience.

Every design element of the dial is drawn directly from the original Datsun 240Z rally car: the colour scheme, the instrument panel font for the chronograph numerals, and the Datsun logo displayed prominently on the dial. A three-dimensional engraving of the winning car appears on the caseback alongside the limited edition number. The bi-colour aluminium bezel carries the tachymetre scale — a direct functional reference to the rally timing heritage of both the Speedtimer and the 240Z. Powered by the in-house V192 solar calibre, accurate to ±15 seconds per month with a 6-month power reserve at full charge, the SSC957P1 is as capable in performance as it is compelling in design.

Why You'll Love It

The SSC957P1 is one of the most narratively rich limited edition watches Seiko has produced in recent years — a piece where every design decision references a specific moment in Japanese motorsport history. The Datsun logo on the dial, the instrument panel font on the chronograph numerals, the three-dimensional winning car engraving on the caseback, the rally colour scheme — these are not decorative gestures, they are direct visual quotations from a 1971 East African Safari Rally victory that both Seiko and Nissan were part of together. The V192 solar calibre eliminates battery concerns entirely, the tachymetre gives it genuine motorsport utility, and the sapphire crystal keeps it pristine for the long term. With only 4,000 pieces and a Datsun 240Z special presentation box, this is a watch for the collector who loves Japanese automotive heritage as much as Japanese watchmaking — and those two things have never been brought together more convincingly than here.

The Story Behind the Datsun 240Z and Seiko Speedtimer

In 1969, two Japanese performance milestones arrived in the same year: the Seiko Speedtimer chronograph and the Nissan Datsun sports car range. Two years later, their paths crossed in one of the world's most demanding motorsport events — the East African Safari Rally, a gruelling multi-day race across the roads of Kenya, Tanzania, and Uganda that was notorious for destroying machines and breaking drivers. The Datsun 240Z, carrying the Seiko logo on its bodywork, won. That victory defined both brands' credentials for resilience and performance under extreme conditions, and the SSC957P1 is the first watch to commemorate it as a limited edition collaboration — over fifty years after the race was run.
