A timepiece that tells the moon
The Citizen Tsuki-Yomi Moonphase BY1010-81L brings the allure of the moonphase to the wrist, combined with a vocation as a travel watch. The blue dial, with luminescent hour markers and hands, dialogues with the world time function and the perpetual calendar, making it a complete companion for those who love technique and seek an understated, elegant aesthetic. A model designed for the man who wants to read time, date and sky in a single glance.
Radio-controlled Eco-Drive: energy from light, precision from the airwaves
The heart of the BY1010-81L is light-powered Eco-Drive technology: the watch turns any light source, natural or artificial, into energy, with no need to replace the battery. To this autonomy is added the radio-controlled function, which automatically synchronises the time with the reference time signal for constant precision. A movement that combines the Citizen heritage in solar watchmaking with the convenience of a timepiece that is always aligned.
Super Titanium Duratect and sapphire crystal: built to last
The case and bracelet are made of Super Titanium with Duratect surface treatment, for a light structure resistant to scratches. The anti-reflective sapphire crystal protects the dial, while the screw-down case back and crown guarantee a water resistance of 10 bar, on a case with a 43 mm diameter. Every Citizen is covered by an official 2-year Citizen warranty, extendable by a further 3 years (up to 5 years in total in Italy; abroad, the 2-year warranty applies): at Oreficeria Ravelli, official Citizen retailer in Pompiano, our in-house workshop and our advice are at your disposal for purchase and after-sales service.
