This timepiece is a magnificent artifact from August 1978, as confirmed by the serial number 886310. The Type II collection was developed by Seiko in the late 1970s to offer highly reliable, daily-wear quartz precision to the Japanese public following the initial era of luxury electronic watchmaking. It houses the dependable Caliber 7123, a technical soul engineered with robust metal components that reflect the uncompromised build quality of early Suwa quartz engineering.
The architecture is outstanding, featuring an angular stainless steel case with a brushed hooded lug design that transitions seamlessly into its original multi-link bracelet. The watch stands out due to its striking, deep emerald green sunburst dial accented by polished stick indices, a bilingual English/Kanji day-date window at 3 o'clock, and the iconic applied single-quartz crystal crest. This professional-grade daily vintage instrument was created exclusively for the Japanese Domestic Market (JDM).
