The Japanese had the first quartz watch on the market.
Although the Swiss were the first to make a quartz watch prototype, the Japanese Seiko 35SQ Astron was the first analog quartz watch to reach the market. Seiko had been a maker of mechanical watches since the end of the 19th century, introducing the first Japanese pocketwatch in 1895 and the first Japanese wristwatch, the Laurel, in 1913.
While continuing to produce mechanical watches, Seiko turned its attention to quartz timekeeping in 1958 with the development of a quartz crystal clock. A team was assembled in 1959 to develop a quartz watch. The primary objectives of the project were to reduce the size to that of conventional mechanical watches, and to achieve reasonable prices through volume production. The result of this project was the world's first quartz watch, the Seiko 35SQ Astron, introduced to the Japanese market on Christmas Day, 1969.
