Citizen Eco-Drive Radio Controlled World Time CB0273-11H - 2010s - 43mm Citizen Eco-Drive Radio Controlled World Time, reference CB0273-11H. A rose-gold-tone stainless steel world timer driven by the solar-powered, atomic-synced caliber H145 beneath an anti-reflective sapphire crystal. The brown-to-grey gradient dial carries a full 26-city world-time ring and a date window at 3 o'clock. Citizen's radio-controlled Eco-Drive line is built around a watch you never set and never battery-swap: the H145 charges from any light and corrects itself daily against atomic time signals from transmitters in Europe, Japan, China and North America. The CB0273 is the dressier end of that family, pairing a warm rose-gold case and leather strap with the sportier steel-bracelet variants' technical core. The 26-zone world-time scale and perpetual calendar good to 2100 make it a genuine traveller's piece under a classic round profile. As a current-catalogue reference, this is a chance to own a fully functional example below new retail. - Movement: Eco-Drive solar quartz, radio-controlled, caliber H145 - Functions: Hours, minutes, seconds, date, world time (26 zones), perpetual calendar - Case: Rose-gold-tone (gold IP) stainless steel, 43 mm excl. crown, approx. 10 mm thick - Crystal: Anti-reflective sapphire - Dial: Brown/grey gradient, applied rose-gold indices, luminous hands - Strap: Brown crocodile-pattern leather, gold-tone pin buckle, approx. 20 mm lugs - Water resistance: Rated 100 m / 10 ATM as marked — gaskets untested, treat as splash-resistant - Era: Modern, 2010s–2020s production Honest, used condition and fully working. The movement runs and the radio reception and Eco-Drive charging operate correctly, the sapphire is clean, and the dial is unmarked. The main wear is on the case finish: the rose-gold IP coating shows rubbing through to the base steel on the lug tips and around the bezel edge, and the leather strap is worn with surface cracking and fading — easily swapped for a fresh 20 mm strap.
