Prospex Speedtimer, Datsun LE

The 1960s and 70s were formative decades for both the Japanese car and watch industries, and Seiko’s latest three Prospex Speedtimers pay homage to that period and one of its most iconic sports cars: the Datsun 240Z. Seiko has a long history of sports timing, including in motorsports. Indeed, Seiko are currently the official timing partner of Australia’s very own Supercars Championship. But let’s go back to 1969, at a time when Japanese car makers were starting to find real success in international motorsports. It was in this year that Seiko introduced the Speedtimer, the world’s first automatic chronograph with both a vertical clutch and a column wheel.
