The Prospex Speedimer line from Seiko has reflected the connections of the brand to motorsport and its permanent commitment to precision. Seiko builds on this inheritance for 2025 by celebrating its common history with the Japanese car manufacturer Datsun, a partnership that goes back to the Golden era of the late 1960s and early 1970s. In addition to the Special Datsun-Hematical Time-and-Datum-Spb517 in Limited Edition, Seiko is presenting two new references of the model, the SPB513 and SPB515, in which vintage-inspired design combines with practical timing functions in a refined everyday sports watch.
Both new Speedimers, SPB513 and SPB515, hold balanced proportions with a 39.5 mm precision steel housing, which is protected by Seiko coating to resist everyday wear. With 12.0 mm thick you remain the original Speed timer Silhouette from 1972, which inspires your retro charm. A defining functional detail is the internal rotating countdown bezel, which enables precise persecution of crucial intervals and is operated at 4 a.m. via an additional crown. A similar function can be found on the prospex alpinist, only there it served as a compass panel. A curved sapphire crystal with inner anti-reflecting coating is clear in light light, while the rear screw cover and the 200 m water resistance ensure that these speedmembers are effective in any environment.
The SPB513 and SPB515 dials are crispy and readable, whereby sharp hands and markings are picked up against silver-white or black background. The inner countdown scale, which adds functions without disorder, underlines the last 15 minutes in orange. Applied indices and precise printing are expected, while Lume keeps clues visible after dark. A pop of orange at the head of the central second pointer adds a sporty note, and a round date window at 4:30 a.m.
The new prospex Speedimer SPB513 and SPB515 house the reliable caliber 6R55, a modern automatic movement that offers 72 hours of electricity reserve. With 21,600 vibrations per hour with a magnetic resistance of 4,800 A/m, it is robust enough for daily life and weekend trips. As with most of the Seiko prospex watches, the movement is covered by a solid fallback.
Both new references are worn on a vintage multi-row-steel bracelet in the vintage style, which is designed for comfort and safety with a triple closure and a push button publication. Available as continuous production models and inexpensive 1,000 EURThe Seiko Prospex Speedtimer SPB513 and SPB515 stand next to the Datsun-Liberied SPB517, which is true to Seiko's Motorsport Spirit and combines classic inspiration with modern engineering.
