Solar Chronograph Datsun 240Z Limited Edition

Limited edition of 4,000 pieces

From Seiko:

The first model of Datsun 240Z was made in 1969,
the same year the Speedtimer was created.

In 1971, adorned with the Seiko logo, the Datsun 240Z with No.11 on its side conquered harsh terrain as it raced 6,200 kilometers to victory in the East-African Safari Rally,
widely regarded as one of the toughest races in the world.

In 1969, Seiko introduced the Speedtimer, the world’s first automatic chronograph equipped with both a vertical clutch and a column wheel, two features that greatly enhanced the measurement of elapsed time.

Today, three limited-edition watches drawing on a range of Seiko technologies join the Speedtimer series, paying homage to the shared legacy of Seiko and Datsun 240Z and their advancements in the late 1960s and early 1970s.
