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 made wall clocks, but eventually shifted focus to pocket and wristwatches.
First Japanese Wristwatch
In 1913, Seikosha introduced the Laurel, the first wristwatch made in Japan. This was a significant milestone, as Japan had no watchmaking tradition at the time. The company became a pioneer in its country and laid the foundation for what would become a renowned name in the global watch industry.
Technological Innovation and Quartz Watches
In 1969, Seiko revolutionized watchmaking 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 gained popularity and remains a standard in today’s watchmaking.
Precision and Reliability
Over the years, 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 regarded for their durability and resilience in extreme conditions.
Seiko has carved out a special place in the watch industry, blending tradition and technology at affordable prices, offering everything from simple models to high-end pieces with its Grand Seiko line.
