What a crazy movement. From the 1990s when quartz was the future and fifteen seconds a month was so much better than cosc that it probably didn't seem worth trying to improve the accuracy of quartz, this movement packs everything the 7t movements were doing with six hands into a three hander. Turn the crown to change modes and the hands swirl around to the appropriate point on the dial. When you're done, they smoothly pick up the time again. There is a perpetual calendar, chrono, timer and alarm. There's even a mode where the hands just dance for the hell of it.
Absolutely bonkers. I can't believe this example is as clean as it is. I've been after one for a while and I got lucky with this. I like watches that contain abandoned technology and I love JDM discontinued models.
This came in a few different versions including a Sus, but I think this is the one.
