Suggested retail prices range from 137,500 yen to 473,000 yen (tax included). Challenge to the World – Seiko and the Datsun 240Z – The 1960s were a historic period for Seiko, as the company made great strides in timekeeping technology, working closely with athletes challenging themselves to time even the tenths of a second at international sporting events. In 1964, Seiko incorporated a stopwatch function into a wristwatch and released the Crown Chronograph, Japan’s first chronograph. Five years later, in 1969, Seiko released the 1969 Speed-Timer, the world’s first automatic chronograph equipped with a vertical clutch and column wheel. The vertical clutch reduced misalignment and jumping of the hands when starting and stopping, while the column wheel provided a reliable feel and stable operation, achieving superior timing accuracy. At the same time, the Datsun 240Z, released in 1969, became a huge hit not only in Japan but also around the world, particularly in the North American market, establishing Nissan’s position as a global image leader. Subsequently, with the intention of demonstrating its high performance as a sports car, the Datsun 240Z began competing in the World Rally, a grueling motorsport competition. Seiko, empathizing with the car’s single-minded determination to continue challenging the world, supported the Datsun 240Z’s motorsports activities in the early 1970s. In 1971, the Datsun 240Z, bearing the SEIKO logo and car number “11,” won the East African Safari Rally, known as the world’s most grueling race, covering a total distance of 6,200 km, making its name known around the world. In honor of the majestic figure of this Japanese brand that took on the world in the 1970s, the long-awaited
collaboration between Seiko and the Datsun 240Z has finally come to fruition.

What is DATSUN? This was a new brand name born in 1932 at DAT Motor Company, the predecessor to Nissan Motor Co., Ltd. The company’s predecessor, Kaishinsha, used the “DAT” brand, which was an acronym for the three investors. The name was initially “DATSON,” meaning “son of DAT.” However, because “SON” was associated with “loss,” the name was quickly changed to “SUN” (sun), and then to “DATSUN.” ≪Product specifications≫ Seiko Prospex Speed Timer Mechanical Datsun 240Z Collaboration Limited Edition Model Image
