Spring Drive is a movement technology developed in-house by Seiko Epson, formerly known as Suwa Seikosha, in the Nagano Prefecture of Japan. Development of the technology started in 1977, and debuted in 1999 in limited quantity in Japan. In 2004, Spring Drive became available globally in Seiko, Credor and Grand Seiko watches. At the June 3, 2019, meeting of the Horological Society of New York, Joseph Kirk will discuss the many hurdles that Seiko overcame with Spring Drive before it could be introduced to the world.*
Spring Drive movements combine the best aspects of mechanical watchmaking, such as the power source of a wound mainspring, along with a unique regulating system as its escapement. The precision of a quartz oscillator and an electromagnetic braking system provide extremely high accuracy and unidirectional motion, with no collision. This is solely achieved with the mechanical energy derived from the mainspring, eliminating any need for a battery. The end result is a spring driven watch that achieves quartz like accuracy. This unique movement type expresses time unlike others, with a completely continuous gliding seconds hand with no sweep or tick.
