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 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 blue 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 metres. Calibre H874.

Reviews
Another beauty for my collection
I love this watch. Great look, great price. It came sized perfectly. Only worn it once and had many compliments. I love it. I rotate my watches to give all an opportunity. This one i might wear the most.
Beautiful watch
Bought this as a gift for my husband and he loves it. Beautiful watch. Pictures didn’t do it justice.
Perfect watch for me
Works perfectly and was very easy to set up. I let the watch syns itself to the Colorado signal and only had to change it to auto DST.
Great watch!
I am very happy with my purchase of the Tsuki-Yomi A-T watch. I received it only four or five days after purchase, and I live in Florida. When I opened the box, it looked complicated to set, but after I Googled it, I was able to set it in less than 5 minutes. I especially like the charge level gauge. I don't understand the moon phase yet, but it makes the watch stand out. It's a great watch.
