Tsuki-yomi A-T
Atomic Timekeeping / Super Titanium
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 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 deep purple 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 a 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 metres. Calibre H874.

Reviews
Love that Citizen came out with a purple variant of this watch! It's so light on the wrist (especially on a rubber strap) that I find myself checking to see if it's still there. The legibility is great as is the information displayed. Definitely a fun watch to add to the collection.
Tsuki-yomi A-T Watches Are Amazing
With this new addition, I now have all the colorways currently available of this watch. Super titanium case and bracelet make this watch super light on the wrist. The atomic timekeeping caliber ensures time is always accurate. The moonphase feature is really cool. This is a watch you should have in collection.! Once you have one you will want all 5 of the colorways like me! I have 65 Citizen watches in my collection, by far the most of any brand in my total collection. The quality, design, features are the best. Most of my watches are atomic timekeeping which provides great accuracy! I love the Super Titanium watches they have. With Duratech the Super Titanium is superior to regular titanium. Citizen customer service is great too!
Beautiful watch!
I have several of watches and this one is my favorite! The purple face is super clean! I’ll be wearing this more than my Tag Heuer watches.
Excellent Feature Packed Timepiece
The Tsuki-yomi is an excellent timepiece. The titanium construction makes it so lightweight and comfortable that you can forget you have it on. I was able to easily set my timezone and it received a good radio signal overnight bringing it within about 2 seconds of the time as checked via the internet. It looks stunning, feels fantastic, and is a true "grab and go" watch since I pretty much will never need to set it!
This watch is over the moon!
I love this watch. I got it two weeks ago, and it has hardly been off my wrist. Incredible accuracy, beautiful design, and titanium toughness secure the top spot in my collection for the Tsuku-yomi A-T Moonphase. When I first set it, the watch, it was the New Moon, and there was not a fingernail visible on the subdial. It has been cool watching as a mini moon face slowly waxed onto my watch until it reached Full Moon today. You know you want it with the purple dial. Go on! Get it!!!
