Product Description
When breakthrough technology and spectacular design meet, the Tsuki-yomi A-T is reading the moon. It’s the world’s first moonphase watch combined with atomic timekeeping innovation from Citizen, and this 30th Anniversary model is nothing short of impressive. The styling embodies the moon’s surface and a window at 6 o’clock displays the current moon phase. The timepiece measures 43mm in a silver-tone Super Titanium™ case, where sharp faceted edges pair with an elevated design throughout for an eye-catching aesthetic on the wrist. The gray dial works in tandem with black accents and silver-tone touches for a display that’s as handsome as it is legible. In addition to its running time, the watch features a moon phase display, world time in 24 time zones, a perpetual calendar, and day-date functionality. Powered by Citizen’s proprietary Eco-Drive technology to provide light-powered vitality without ever needing a battery. Water resistant up to 100 meters. Caliber H874.

Excellent craftsmanship!
Just purchased the Tsuki-Yomi A/T and I'm very pleased. The watch is very well made and the super titanium construction makes it very light and comfortable to wear. I never have to worry about setting it because every night without fail it recieves the signal from Fort Collins and updates the time. I now use this watch to set all my automatics in my collection. Alot of watch for the money!
Citizen Response Thank you for the terrific review. We hope you enjoy your Tsuki-yomi for years to come!
Excellence in a watch
The Tsuki~Yomi watch by Citizen is wonderful. It’s classy and stylish without being ostentatious. The moon on the face looks nice and is not overwhelming to the overall piece. The titanium makes the watch feel much lighter than it looks and is a good choice for most occasions. Definitely one of my favorites. The atomic clock feature means you never have to set it but even if you don’t get a signal, it still works just fine. I like having it in my rotation and expect to get decades of use. Fantastic watch.
Citizen Response Thank you for the glowing review of the Tsuki-yomi and it's many amazing features. Enjoy!
