Swatch Labirinto

How often does one get to come across a Swatch AutoQuarz? Go in any Swatch Shop and you'll find the Originals, the Skins, the Chronos, the flik-flaks, the Beats, the Ironys, etc. but an AutoQuarz? I reckon it's as rare as a Swatch Solar. So when I saw the Labirinto (STK404) on sale, I just have to buy it.

Had a pretty nasty experience with Swatch's plastic battery compartment breaking off, that's why I'm using an Irony. I'm sure it's not gonna happen to the AutoQuarz because there is no battery! As the name implies, it's an automatic but it uses a normal quartz movement. Like an automatic, it uses a rotating weighted half-disc to generate energy (when you move your hands). But instead of storing this energy in a mainspring, it is used to power a micro-generator, which charges a capacitor, which in turn powers the integrated circuit, which makes the quartz crystal oscillate, which controls the timing of the stepper motor, which drives the gear train, which ultimately moves the hour, minute, and second hands.

The Labirinto's back cover is transparent, so you can actually see the rotating weight and a portion of the circuit board and the gears. I also noticed a silver disc which looks very much like a button battery. Hope it lasts as long as the watch.
