Seiko’s latest entry in the Prospex Speedtimer lineup, the SPB513, channels the golden age of motorsport with a contemporary twist. Designed as a tribute to the brand’s storied past with Datsun, this 2025 release merges vintage inspiration with modern mechanics, offering an everyday sports watch that’s built for performance and style. With its 39.5mm stainless steel case and super-hard coating, the SPB513 maintains the clean, compact proportions of the 1972 original while offering modern durability.
The inner rotating countdown bezel, operated by a secondary crown at 4 o’clock, delivers precision timing functionality—a nod to the Speedtimer’s racing roots. Its silver-white dial is crisp and legible, protected by a curved sapphire crystal with anti-reflective coating. A vibrant orange-tipped seconds hand and 15-minute highlight on the countdown scale inject sporty flair without compromising readability. Lume-coated hands and indices ensure visibility in low light, while the 200m water resistance and screw-down case back add rugged dependability.
Inside, the Caliber 6R55 automatic movement powers the Seiko SPB513 with a 72-hour reserve and magnetic resistance up to 4,800 A/m, making it tough enough for the track and the street. The bracelet, a vintage-style multi-row stainless steel band, completes the package with comfort and security thanks to a three-fold clasp and push-button release.
Priced at $995, the Seiko Prospex Speedtimer SPB513 is a precision instrument disguised as a daily driver—perfectly tuned for those who appreciate heritage, performance, and sleek execution.
