Seiko celebrates a golden era of Japanese motorsport with three new Prospex Speedtimer models, each paying tribute to the legendary Datsun 240Z. Combining mechanical innovation, historic design cues and serious collector appeal, this release captures the spirit of speed, endurance and craftsmanship.
A partnership forged in dust and victory
Long before heritage reissues became a trend, Seiko was already writing chapters of motorsport history, timing endurance races and sponsoring the winning team at the grueling East African Safari Rally in 1971. The car that crossed the finish line first? The Datsun 240Z, a machine that embodied the same values as Seiko itself—reliability, precision, and performance.
This new trilogy of watches draws from that shared DNA. Designed not just as nostalgic novelties but as serious sports watches, the Speedtimer x Datsun collection celebrates two icons of Japanese engineering born in the same pivotal year: 1969. One reshaped the world of chronographs. The other conquered rally stages across continents. Together, they now fuel a modern-day tribute with unmistakable character.
Three movements, one story
Leading the pack is the SPB517, a time-and-date Speedtimer that introduces a new format to the collection. Its 39.5mm steel case with hard coating houses a dial inspired by vintage rally timers, complete with an inner rotating countdown bezel operated via a secondary crown. The Datsun logo sits proudly above 6 o’clock, while bold markers and LumiBrite-treated hands ensure clear legibility. Powered by the automatic calibre 6R55 with a robust 72-hour power reserve, it’s a practical daily driver with a historical twist. Paired with a perforated black leather strap with red lining, it’s limited to 2,500 pieces, priced at €1,250.
For purists, the SRQ057 delivers a true mechanical chronograph experience. The 42mm stainless steel case is treated with a matte black hard coating, giving it a stealthy, motorsport-ready look. The bezel—unlike previous Speedtimers—is fixed and external, echoing classic racing chronographs. The dial layout includes sub-dials at 3, 6 and 9, with red highlights for the chronograph functions and a slim, blue-striped running seconds hand. Inside beats the in-house 8R48 calibre, a 4Hz chronograph movement with a column wheel and vertical clutch, offering 45 hours of autonomy. On a black leather strap, limited to 500 pieces, it’s the most exclusive—and mechanically advanced—model of the trio. Price: €3,500.
Completing the lineup is the SSC957, a solar-powered chronograph that maintains the racing aesthetic while adding everyday practicality. Slightly smaller at 41.4mm, it features a black dial with red accents, a fixed tachymeter bezel, and three sub-dials including a power reserve indicator at 6 o’clock. It runs on the solar calibre V192, offering six months of power after a full charge. Mounted on a steel bracelet with black center links, it’s limited to 4,000 units and retails for €1,050.
Who are these watches really for?
This collection isn’t just a marketing exercise—it’s a genuine celebration of Seiko’s racing legacy and a reminder that modern tool watches can still have a soul. Each model brings something different: the SPB517 offers vintage functionality and minimalist charm; the SRQ057 is a serious mechanical chronograph with racing roots; and the SSC957 is for those who want reliability and style without winding or charging anxiety
Design-wise, these watches aren’t loud—but they speak with confidence. From the retro font on the bezels to the subtle but effective color contrasts, everything has a purpose. The Datsun logos add depth to the narrative, while the quality of finishing and mechanical specs remind us that Seiko Prospex continues to punch far above its weight class.
Final thoughts, pricing & availability
Seiko’s Speedtimer x Datsun trilogy is one of the most authentic and compelling automotive-themed watch releases in recent memory. It avoids the usual trap of surface-level storytelling and delivers real mechanical depth, wearability, and collector-grade exclusivity.
Prices range from €1,050 to €3,500, with availability starting August 2025 in Seiko boutiques and selected authorized retailers. Given the historical context, limited production, and variety of formats, these watches are bound to attract attention across the board—from hardcore Seiko fans to vintage car enthusiasts. This is not just another throwback. It’s a celebration of two Japanese legends that once raced—and won—together.
