Tsuki-yomi A-T
Atomic Timekeeping / Super Titanium
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 grey 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.

Great watch
I am happy with my watch. Before receiving the watching, I was a little worried about the atomic signal not automatically syncing, but it has synced every night without issue. The only thing I would warn people about it do not attempt to resize on your own. I did not realize that the links had collars and pins, rather than just the normal pins with one end larger than the other. I was able to take to a jeweler and they took care of me without issue. All in all, great watch.
Amazing watch love the accuracy and it’s lightweight very nice watch worth the buy.
Another amazing timepiece from Citizen.
I own 21 citizen watches which I have been collecting for over 45 years and this model is a great addition to my collection being the first Citizen to display moon phases. It is attractive, light and "bulletproof" being encased in super titanium!
Great moon watch!
This is a great moonphase watch that once one gets it and puts it on it looks better in person than it does online. There's plenty of room for size adjustment and it is lighter than other stainless steel watches I've owned of about the same size. All together, it was a great purchase.
