Prospex Speedtimer Solar, Datsun LE

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.
By operating the 4 o'clock crown, a countdown timer function can be used to measure key intervals in motorsports competitions, such as the time remaining before the start and target durations for tasks such as tire changes and refueling. Inspired by the color of rally cars, which minimizes light reflection, matte black is used for the dial, while red accents are added to the second hand and dial ring to enhance legibility. The Arabic numerals on the dial ring take inspiration from the font used on the Datsun 240Z dashboard. The leather strap is sourced from tanneries certified by the Leather Working Group, of which Seiko is a member. The seams on the inner sides of both of the leather strap is covered with lining to minimize damage from sweat and water.
