Old retro watch that debuted in 1975, really beautiful but had lots of problems, eg only 10 day battery lifetime while claiming 1 year (and batteries hard to replace). Could be bought as a kit or fully assembled. Reminded me of a watch I did a while ago, with a HPDL-1414 display and a msp430: https://www.youtube.com/watch?v=H-n53o-2VUA https://www.youtube.com/watch?v=H-n53o-2VUA
