This timepiece is a magnificent artifact from September 1976, as confirmed by the serial number 691631. The King Quartz series was defined by its uncompromising quality and a breathtaking deep charcoal black dial that exudes executive authority. It is powered by the high-grade Caliber 0853, a movement engineered with surgical precision to provide maintenance-free accuracy and a specialized quickset day-date function for the elite urban explorer.

The design follows the "Grammar of Design" principles, featuring a sharp, unpolished stainless steel case with multifaceted lugs that reflect light with dramatic contrast. The dial is a work of high-end JDM art, featuring the iconic double-honeycomb quartz logo at 6 o'clock and a dual Kanji/English day-date wheel. Flipping the watch over reveals the specialized external battery hatch on the caseback, allowing for easy service without exposing the movement—a hallmark of Seiko's high-end early quartz engineering.
