The Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition (ref. spb517j1) is an automatic chronograph watch, with a 39.5mm stainless steel case, 12mm thick, powered by the 6R55 movement and a 72-hour power reserve. Water resistance is rated to 200m, under a sapphire crystal. Manufacturer MSRP is $1,150.
The Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition is praised for its vintage racing concept, applied markers, and dial that shifts from cream to silver with orange accents. Owners appreciate the Datsun logo, dual crowns, and internal countdown bezel, with some noting Seiko's finishing is top-notch. However, some find the dial text cluttered, particularly "automatic 3 days," and consider the price point too high. The watch features a 42mm black-coated stainless steel case, an external tachymeter bezel, and Seiko's 8R48 automatic chronograph movement with a 45-hour power reserve. On balance, owners rate the Seiko Prospex SPEEDTIMER Mechanical Datsun 240Z Limited Edition well for its unique vintage concept and quality finishing, though price remains a point of contention for some.
