When advanced technology and spectacular design meet, the Tsuki-yomi A-T reaches for the moon. This 30th-anniversary model is simply stunning, as it is the world's first moon phase watch combined with Citizen's atomic timekeeping innovation. Its style embodies the surface of the moon, and a window at the 6 o'clock position displays its current phase. The 43mm watch comes in a silver Super Titanium™ case, where sharp faceted edges combine with an enhanced design for an eye-catching aesthetic on the wrist. The deep red dial is paired with black accents and silver touches to provide a display that is as beautiful as it is legible. In addition to its operating time, the watch offers a moon phase display, world time in 24 time zones, a perpetual calendar, and a day and date indicator function. Featuring Citizen's exclusive Eco-Drive technology, it is powered by the vitality of light, with no battery needed. Water-resistant up to 100 meters. Caliber number: H874.
