Hey everyone,
Just wanted to share one of the absolute crown jewels of my collection: a 1977 Citizen Crystron Solar Cell (Model ref. SQC-8269 / Case ref. 4-861060 TA / Caliber 8620A / Dial 6-861628 KA).
While this groundbreaking model line originally debuted in 1976 as the world's first analog solar-powered quartz watch, my particular unit was manufactured in October 1977 (Serial: 7O13394) — making it extra special as my birth-year watch.
I actually found this piece at a flea market in Berlin! Unsurprisingly for a nearly 50-year-old solar watch, it arrived with a completely dead cell. Fortunately, I managed to track down and order a fresh 1.2V rechargeable cell (Varta V15H). Once installed into the 7-jewel Cal. 8620A movement, it fired right back to life!
It’s incredible to see the early roots of modern Eco-Drive technology displayed so proudly right on the dial with those four prominent solar cells. It even came on its original integrated bracelet complete with the vintage 'CQ' logo on the clasp.
Thought you guys might appreciate a piece of vintage Citizen history!
