To overcome the problem, engineers from Seiko have come up with a genius solution, they have built a hybrid watch movement using electronic technology and mechanical system. In a normal mechanical movement, the mainspring is the primary source of power and its job is to send power to the escapement and enabling the escapement to regulate the power sent to the gear train. Things are a little different for electronic-driven watch movement, the Seiko Electronic 3700 movement power comes from the battery and the transistor inside the watch was design to alternate/switch the current pass to the induction coil next to the balance wheel of the watch. The balance wheel was fixed with two permanent magnets so that it will react to the magnetic induction from the coil. The balance wheel will then be driven back and forth like in a mechanical watch. This is such a genius and elegant technology!
As a result, the second hand on Seiko Electronic EL370 watch are ticking smoothly just like a fully mechanical watch. The upside is that you will no longer have to worry about the stopping of your watch after taking it off your wrist for a more sporty watch during the weekend. The Seiko Electronic EL370 is always ready and good to go.
When we look at the Seiko Spring Drive as a technological advance hybrid movement, I will consider the Seiko Electronic EL 370 (3700) movement as its ancestor as it is a demonstration of how Seiko's spirit of using technology to drive their advance movement technology. The Seiko Electronic watch is a short-lived series which then replaced by the Seiko Quartz watches that brings the Quartz Crisis to the whole watch industry. The short production plus the interesting movement technology makes the Seiko Electronic EL370 extremely collectable in my point of view.
