The Seiko SPB517J1 merges precision watchmaking with the spirit of automotive performance. Inspired by the 1969 launch of the Speedtimer and Nissan’s legendary Datsun sports cars, this limited edition celebrates a shared legacy of innovation and endurance. Its 39.5 mm stainless steel case with super-hard coating houses the advanced in-house 6R55 automatic calibre, offering a 72-hour power reserve and 200 m water resistance.
Design cues echo the Datsun 240Z rally car, including its distinctive colour palette, tachymeter-equipped bezel, and finely detailed dial under curved sapphire crystal. Lumibrite accents enhance legibility, while the soft black LWG-approved leather strap provides comfort and style. Compact yet powerful, the SPB517J1 is a refined sports chronograph created for enthusiasts who value precision, resilience, and timeless automotive-inspired design.
