SEIKO PROSPEX SPEEDTIMER MECHANICAL - SPB513J1

Seiko's Prospex Speedtimer line has long reflected the brand’s ties to motorsport and its enduring commitment to precision. For 2025, Seiko builds on this legacy by celebrating its shared history with the Japanese carmaker Datsun, a partnership that harks back to the golden era of the late 1960s and early 1970s. Alongside the special Datsun-themed limited edition time-and-date SPB517, Seiko introduces two new references of the model, the SPB513 and SPB515, blending vintage-inspired design with practical timing features in a refined everyday sports watch.
