This timepiece is a significant artifact from the era when quartz technology was brand new and highly prestigious! The Citizen Crystron line was Citizen's premier quartz offering in the 1970s and 1980s, designed to showcase the ultimate in timekeeping accuracy. The watch is likely powered by the robust Citizen Caliber 8620 (a later, high-quality revision of the 8600 series), which provides excellent grab-and-go accuracy with exceptional reliability. The deep Navy Blue Dial is highly stylish, framed by prominent white Roman numerals and a unique television-shaped case that perfectly captures the bold aesthetic of the mid-1970s. The movement's inherent efficiency allows the case to remain slim and discreet, despite its bold profile. This is an excellent acquisition for a collector who appreciates pioneering quartz technology and the distinctive design of Citizen's vintage JDM line.
