Description from the seller
CITIZEN Tsuki-Yomi Eco-Drive Radio-Controlled Moon Phase Grey Dial Men's Watch
when technology meets astronomy.
The Citizen Tsuki-Yomi Moon Phase interprets contemporary watchmaking through an interesting balance between precision.
The heart of the watch is the Eco-Drive H874 movement, powered by light and equipped with global radio control. Synchronization with reference time signals allows for high precision, while the perpetual calendar and the World Time function across 24 time zones make the movement particularly versatile.
The most fascinating element is the automatic lunar phase calculation system, with a double display adaptable to the northern or southern hemisphere. A technological solution that reinterprets one of the most evocative complications of traditional watchmaking.
The steel case with a gray-plated finish gives the model a contemporary character, enhanced by the sapphire crystal and the steel bracelet.
With a thickness of just 10.7 mm, the Tsuki-Yomi maintains balanced proportions despite the complexity of its functions.
This watch demonstrates Citizen’s ability to transform advanced technologies into an intuitive user experience, offering a timepiece that combines the charm of lunar phases with the practicality of a radio-controlled Eco-Drive watch.
TECHNICAL FEATURES
The Citizen Tsuki-yomi Moon Phase is a radio-controlled Eco-Drive watch with a gray dial, steel bracelet with dark finish, and double safety clasp, and a 42.00 mm steel case.
The automatic lunar phases function, perpetual calendar, and radio synchronization make it a technical timepiece designed for everyday use without frequent adjustments.
This Citizen Eco-Drive H874, powered by light, requires no periodic battery replacement, radio-controlled with automatic synchronization in reception areas.
Automatic indication of lunar phases, with the possibility to select northern or southern hemisphere.
Perpetual calendar up to February 28, 2100 and World Time in 26 zones.
42 mm case and high-resistance anti-scratch sapphire glass
Gray dial and steel bracelet with dark finish and double safety clasp.
Water resistance 10 bar / 100 m.
Tsuki-yomi Moon Phases: reading the Moon cycle
The Tsuki-yomi Moon Phase collection blends aesthetics and technology through the representation of lunar phases. The H874 caliber automatically calculates the Moon phase based on the received time information and allows the appearance of the indication to be adjusted according to the North or South hemisphere, with manual correction when necessary.
The Citizen Eco-Drive H874 movement draws energy from natural or artificial light: it does not require periodic replacement of a traditional battery. When fully charged, it offers about 6 months of autonomy, which can extend up to 2.5 years in power-saving mode. The radio-controlled system supports time signals from Germany, Japan, the United States, and China, compatible with geographic location and reception quality.
Perpetual calendar and World Time
Highlights include the perpetual calendar up to February 28, 2100, day of the week, date, 24-hour dial, and world time for 26 zones. There are also the power reserve indicator, daylight saving time management, shock detection, automatic hand correction, and anti-magnetic protection.
New watch, complete with box, and official dealer warranty of 2 + 3 years.
