This timepiece is a magnificent artifact from the 1980s, representing Citizen’s mastery of the timeless "Datejust" silhouette. The reference 6100-S28569 is defined by its striking gold-toned fluted bezel and a breathtaking champagne sunray dial that catches the light with every movement of the wrist. It is powered by the precision Caliber 6100, a high-reliability quartz heart engineered to provide maintenance-free accuracy and a quickset day-date function, proudly displaying the "CQ" logo that signified Citizen's top-tier quartz offerings of the era.

The architecture is quintessentially refined, utilizing a 36mm stainless steel case and a classic two-tone Jubilee-style bracelet that offers a high-end, tapered feel on the wrist. The dial is a work of high-end Japanese art, featuring hand-applied baton indices and a framed day-date window at 3 o'clock for ultimate executive utility. Flipping the watch over reveals the solid stainless steel caseback with the crisp 6100-S28569 engravings, definitively confirming its authentic Japanese heritage. This is an essential acquisition for an elite collector who appreciates 1980s luxury design, the mechanical soul of a precision quartz heart, and the bold, shimmering presence of the Citizen CQ.
