Citizen Attesa Eco-Drive Moon Phase BY1004-17X

The Citizen Attesa BY1004-17X is a technically advanced timepiece from the Lunar Series, featuring the "Luna Program"—the world’s first fully automatic analog moon phase function for light-powered watches. This system calculates the moon phase daily based on radio signals received from atomic clocks. The watch is crafted from Super Titanium™ with a Duratect DLC (Diamond-Like Carbon) coating, ensuring it is both incredibly lightweight and highly resistant to scratches. Its distinctive copper-toned dial is inspired by the lunar surface, complemented by a sophisticated moon phase display at 6 o'clock. Powered by Eco-Drive technology, it offers global radio-controlled accuracy and is paired with a premium black leather strap.
