History of Seiko Prospex SPB243J1
When Kintaro Hattori founded his company in 1881, he was just 21 years old. During his fifty years at the helm, Seiko became the leading watch company in Japan, with its own design and production facilities. This achievement was a direct result of his single-minded vision that Seiko should be “Always one step ahead of the rest”. His words resonate still and continue to inspire Seiko today. Throughout this year, Seiko will release a series of creations that embody the spirit of Kintaro’s words and honor the140th anniversary of the founding of his company. The celebrations start with a series of Prospex, Presage and Astron watches inspired by the landscapes, seascapes of Japan.
From Seiko Prospex, a new series focuses on the beauty of nature. The watches capture the deep green scenery of the rich ocean that surrounds Iriomote Island.
The island of Iriomote in Okinawa Prefecture attracts divers from all areas of the world. Its abundant coral reefs teem with marine life but the island’s special charm lies in the primeval and pristine mangrove forests that surround it. Further, Iriomote is home to several species of flora and fauna that are rare and, in some instances, unique to the island.
History of Seiko
The company was founded in 1881, when Kintarō Hattori opened a watch and jewerly shop called “K. Hattori” (服部時計店 Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha, meaning roughly “House of Exquisite Workmanship”.
The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world’s first production quartz watch, it cost the same as a medium-sized car. Seiko later went on to introduce the first quartz chronograph.
