Seiko’s history began in 1881 in Tokyo, Japan, when a young entrepreneur named Kintaro Hattori opened a watch repair and sales shop. His vision was to create high-quality watches, and in 1892 he founded the Seikosha factory (in Japanese, “Seiko” means “precision” or “success”, and “sha” means “house”). Initially, Seikosha produced wall clocks, but over time they focused on pocket and wristwatches production.
First Japanese wristwatch
In 1913, Seikosha launched the Laurel, the first wristwatch made in Japan. This marked a significant milestone, as Japan had no watchmaking tradition at that time. The company became a pioneer in its country and laid the foundation for what would become a benchmark name in the global watch industry.
Technological innovation and quartz watches
In 1969, Seiko revolutionized the watchmaking world with the Seiko Astron, the world’s first quartz wristwatch. This breakthrough transformed the watch industry by introducing a much more accurate and affordable technology than traditional mechanical movements. Quartz technology quickly became popular and remains a standard in modern watchmaking.
Precision and reliability
Over time, Seiko has introduced multiple watchmaking innovations, such as the automatic chronograph and the Kinetic charging system (a combination of kinetic energy and quartz technology). It is also known for its dive watches, highly valued for their durability and resistance in extreme conditions.
Seiko has earned a special place in the watch industry by combining tradition and technology at affordable prices, offering from simple models to high-end pieces with its Grand Seiko line.
