Limited to just 500 pieces worldwide, the SRQ057J1 is a striking collaboration that unites modern Seiko watchmaking with iconic car-making heritage in a distinctive 1960s-inspired design. The Speedtimer was first introduced in 1969 as a major innovation milestone, becoming the world’s first automatic chronograph to feature both a column wheel and vertical clutch—technology that remains essential for accurately measuring elapsed time today.
Launched in the same year, Nissan Motor Corporation’s Datsun brand was Japan’s leading sports car manufacturer. In 1971, the Datsun 240Z, also known as the Fairlady Z and proudly displaying Seiko sponsorship, claimed victory in the East African Safari Rally—one of the toughest motorsport events in the world. This legendary car mirrors the Seiko Speedtimer in its blend of style, resilience and reliable high performance, forming the foundation of this unique collaboration.
The SRQ057J1 incorporates authentic design cues from the original DATSUN 240Z rally car, including the colour scheme, instrument-panel inspired font and DATSUN logos on the case back, dial and clasp. A hard-coated bezel with tachymeter scale enhances its motorsport credentials, while contrasting sub-dials beneath dual-curved sapphire glass ensure clear legibility. Powered by Seiko’s in-house 8R48 mechanical chronograph calibre, the 42mm case houses a movement engineered for maximum precision, combining a vertical clutch, column wheel and three-pointed hammer for smooth operation, durability and perfectly synchronised resets. As part of the Prospex collection—‘Professional Specifications’—this limited edition timepiece is designed to be practical, reliable and durable, meeting the demands of true sports and performance enthusiasts.
