The Seiko Prospex Speedtimer Meets 240Z Heritage in New Datsun Collaboration
Starring three limited-edition watches.
Summary
- Seiko unveils three limited-edition Prospex Speedtimer watches with Datsun 240Z
- Designs draw from the car’s red-and-black chassis and vintage instruments
- Releasing in September 2025 , each model will be available in limited quantities
Seiko and Datsun are celebrating their shared legacy with three new Prospex Speedtimer watches, inspired by the late-1960s era in which both brands broke new ground. In 1969, Seiko launched the Speedtimer, the world’s first automatic chronograph to feature a vertical clutch and column wheel. At the same time, Datsun also introduced its now-iconic 240Z sports car. Their partnership was cemented in 1971 when a Seiko-branded Datsun 240Z claimed overall victory in the East African Safari Rally, demonstrating the precision timing and high-performance spirit that underpin these limited-edition timepieces.
Each collaboration model – SPB517, SRQ057 and SSC957 – draws design cues directly from the Datsun 240Z’s red-and-black chassis and vintage instrument fonts. The SPB517, powered by Caliber 6R55, carries a period-correct Datsun logo in a red circle and blue rectangle; the SRQ057, driven by the mechanical chronograph Caliber 8R48, features cursive Datsun lettering alongside an etched rally-car emblem on its case back; and the solar-powered SSC957, with its V192 movement, displays block-style Datsun text and a bespoke illustration of the 240Z. All three watches sit on perforated or lined leather straps sourced from Leather Working Group-certified tanneries.
Functionality harks back to motorsports essentials: the SPB517’s countdown timer measures critical pre-race intervals, the SRQ057 boasts a tachymeter bezel calibrated from 50 to 600 km/h plus the hallmark precision of Seiko’s vertical clutch and column wheel chronograph, and the SSC957 delivers a 60-minute chronograph and 24-hour subdial with up to six months of power reserve on a full charge.
These limited editions, 2,500 units of the SPB517, 500 of the SRQ057 and 4,000 of the SSC957, will be available from September 2025 at Seiko boutiques and select retailers worldwide. For more information, head over to Seiko’s official website.
