Seiko is celebrating a key era in its motorsport heritage with a new collection of its Seiko Prospex Speedtimer models, including three limited-edition watches inspired by the iconic Datsun 240Z rally car. The releases pay tribute to the late 1960s and early 1970s, a period when both Seiko and Datsun pushed boundaries in timing precision and motorsport engineering
The Seiko Prospex Speedtimer name traces back to 1969, when Seiko introduced the world’s first automatic chronograph featuring both a vertical clutch and a column wheel. In the same year, the Datsun 240Z debuted and quickly became a motorsport favourite, famously winning the gruelling 6,200 km East-African Safari Rally in 1971 with the Seiko logo proudly displayed on its No. 11 race car.
Fast-forward to today, Seiko brings the spirit of that era back with three collaboration models and three additional Prospex Speedtimer models joining the main Prospex line-up.
