The History Spring Drive Watches at Seiko
Seiko is one of Japan’s leading watch manufacturers. It was founded in 1881, under the name Seikosha. At first, Seikosha made wall clocks and produced its first pocket watch in 1895. The company changed its name to Seiko in 1929.
Sekio’s latest innovation in the watch industry is Spring Drive. The concept of the Spring Drive watch was first developed in 1977 by Japanese engineers at the Suwa factory of SEIKO EPSON. It took Seiko 28 years to create the first Spring Drive watch. To make the Spring Drive dream come true, all of SEIKO’s expertise in timekeeping has been applied to traditional and electronic circles.
This Spring Drive Seiko watch is a classic mechanical watch. All mechanical watches use a spring as a power source, but the internal mechanism and operation of the Spring Drive is very unique and unusual. It is made using a 300-year-old mechanical escapement technique for time management. The result is a watch that avoids the old problems, associated with mechanical escapements such as hairpins, fragile wheels, forks, and flywheels.
The Seiko Spring Drive watch is fully automatic and does not need to be replaced or battery charged. It is an automatic watch that uses modern technology to control and measure time. Like other mechanical watches to maintain power, it uses a mainspring, a barrel, an independent movement and a winding mechanism. A high-tech system is used to control the time measurement in this watch.
The watch is equipped with a Tri-synchro Regulator, which is used to unwind the mainspring. This controller is used to control three types of power which are the mechanical power of the mainspring, the electric power generated from this mechanical power, and the electric power that drives the rotation of the glide wheel. These three types of forces are the basis of the Spring Drive mechanism.
The power generated by the rotation of the glide wheel is used to drive a control circuit with a quartz crystal oscillator. This, in turn, controls the electro-mechanical braking of the glide wheel. The glide wheel completes 8 revolutions around the controller per second. The speed of the glide wheel is continuously controlled by applying the braking force. This delicate watch was the first of the 2005 Baselworld Exhibition. It was released commercially in stores in September 2005 in the USA, Europe and elsewhere in the world.
