This timepiece is a vibrant example of the Japanese Domestic Market (JDM) "Type II" line, which Seiko launched to bring high-precision quartz technology to a wider, style-conscious audience during the late 70s. This specific reference, 7123-8020, is a showstopper due to its rare emerald green sunburst dial featuring a bold, vertical "racing stripe" through the center, a design element that makes it stand out from the more conservative dress watches of the era. The case design is quintessentially 1970s, with sharp, brushed integrated-style lugs and a slim profile that hugs the wrist perfectly.
The watch is powered by the dependable Seiko Caliber 7123, a workhorse quartz movement known for its longevity and ease of maintenance, featuring a quick-set day/date calendar with the iconic bilingual English/Kanji wheel found only on JDM models. The caseback reveals the serial number 883161, which definitively dates the production of this unit to August 1978. This is a must-have for a collector looking for a bold, reliable vintage piece that embodies the transition from mechanical to high-tech electronic watchmaking with true Japanese flair.
