CITIZEN launched the world’s first light-powered analogue watch in 1976. Now known as Eco-Drive, this groundbreaking technology celebrates its 50th anniversary in 2026. To commemorate this milestone, CITIZEN ATTESA introduces two limited-edition Eco-Drive 50th Anniversary models. Inspired by the green flash, a rare natural phenomenon that occurs as the sun disappears below the horizon, this model captures its fleeting brilliance through advanced structural colour film and vapour deposition technologies. The substantial 44.6mm Super Titanium™ case is finished in sophisticated black DLC with Duratect Amber Yellow accents around the bezel, delivering exceptional strength and scratch resistance while remaining remarkably lightweight. A matching titanium DLC bracelet adds refined lustre, while sculpted chronograph pushers and protective crown guards lend a confident, sporty edge. A vivid green world time sapphire bezel ring marks the first use of vapour deposition to create a dark green colour on an ATTESA watch. Beneath the dial, structural colour film produces shifting green hues as light refracts and reflects across its surface, while an inkjet-printed black layer evokes the brief glow of the green flash above the horizon. Applied markers and a balanced triple-register chronograph layout ensure excellent readability, complemented by a subtle date window between four and five o’clock. The F950’s sophisticated functionality enhances its premium appeal, delivering global timekeeping across 39 cities, dual time capability, UTC display, a perpetual calendar, daylight saving time indication, and both power reserve and light level indicators that quietly underscore its technical mastery. Powered entirely by light through Citizen’s Eco-Drive technology, the watch requires no battery changes, providing effortless reliability alongside enduring style. With water resistance to 100 metres and the exceptional Calibre F950 driving its performance, this limited edition stands as a refined tribute to both cosmic drama and contemporary luxury — a timepiece crafted for those who appreciate precision, craftsmanship, and distinction in every detail. Limited to 1,500 pieces worldwide.
