The Digital Watch: A Brief History - Mechanical Digital Watches - Slideshow from PCMag.com

I'm just getting into watch collecting, and am absolutely in love with the Cortebert Digital Wristwatch. However, I can't seem to find it on sale anywhere online, or even previous sales to gage how much a watch like this would run. Does anyone know where I might be able to track such a watch down? My apologies in advance if my questions are too Noob and break any particular forum decorum.
