This timepiece is a significant artifact from the era when quartz technology was still very new and highly prestigious, representing a higher-grade quartz line just below the Grand Quartz models. The Seiko Quartz QZ, reference 0920-8010, is defined by its striking and unique aesthetic: a circular black inner dial with minimal text, surrounded by a contrasting gold outer ring featuring the hour markers. This "bullseye" or two-tone dial design is a signature look for the early JDM Quartz QZ line. The watch features a sharp, angular stainless steel case characteristic of the late 1970s, often paired with an integrated mesh bracelet (as seen in the image).
The heart of the watch is the Seiko Caliber 0920, a sophisticated, early quartz movement. The QZ line was engineered for excellent reliability and accuracy, setting it apart from standard mass-market quartz watches. The caseback reveals the serial number 597537, indicating a production date of September 1975 (based on the first digit '5' for the year and the second digit '9' for the month). This is an excellent acquisition for a collector who appreciates pioneering quartz technology and bold, unique 1970s JDM design.
