The first watch featuring computer functions

You hardly ever hear from Seiko, these days. I think they were brought up by Epson.

In the 1980s, having a Seiko digital, was like having a Rolex (Or "Rolecks," if you are buying in Times Square).

I became interested in Seiko watches after recently buying a Seiko Astron while visiting Japan. It’s amazing how much they shaped the watch industry. With the Astron series they buried a lot of Swiss manufacturers when it was first launched. Also, their “Spring Drive” technology is amazing. It’s basically the perfect hybrid between a mechanical watch movement and a quartz crystal. The movement is mechanical, with the spring releasing energy and powering the quartz crystal (there is no battery), which in turn acts as a “referee”, applying an electromagnetic brake and regulating the mechanical movement.
