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.

“This is a great daily watch that pairs well with everything. The accuracy of an atomic watch can't be beat. The titanium build makes it lighter than a mechanical watch.”

“The watch is fabulous. I’ve been admiring it for quite some time. I took advantage of a special offer. They were running. I absolutely love it. The only downside due to me not being informed was the watch is very light as it is made of titanium. It definitely feels different than my heavier watches, and it took me getting used to it but my initial reaction was a little let down. After researching and understanding it’s just native titanium instead of the dense stainless steel like my other watches I’ve come to appreciate this aspect of it overall, if you are a moon enthusiast, a moon, goddess, lover or admire the moon this is a fabulous watch.”

“I own several ProMaster Citizen watches, but this was my first Citizen titanium watch. Changing the band links was easy and the moon phase feature is really great. I am very happy with my purchase.”

“First off this is a technical marvel for a non-smartwatch. My watch collection includes Rolex Datejust and Omega Seamaster. I stumbled across this Citizen when searching for watches with moon phase functionality. My daily wear watch has been an original swiss made automatic Invicta diver i purchased for $800 twenty years ago. The watch can be a pain if I left it in the drawer for a few days. I’d have to catch it up by resetting it and the date. I’ve decided to use my Citizen as my everyday watch. Once it’s set & synchronized it’s completely carefree. There’s no battery to worry about replacing, charging or rewinding it. It syncs daily in the early hours, but once it’s set it will keep time. I really like the moon phase on the dial. It’s very lightweight as others have pointed out. The positive is it’s light, but it also gives the illusion it’s a cheap watch. I like the watch face being a rendering of a moon. I wish it was a little sharper. I would like the bracelet to be shinier. It almost seems like it’s slightly tarnished. I cleaned the bracelet to be sure it wasn’t. I would also like the crystal dome to be sharper in appearance. But those are cosmetic. I purchased it for its carefree function to use everyday. I’m happy with that most of all. I wouldn’t buy the watch at its original price if $850, but it’s a good value if it’s on sale in the $600 range.”

“I couldn’t be happier with my Citizen Tsuki-yomi A-T. The craftsmanship is exceptional — the titanium build feels incredibly light yet durable, and the moonphase dial with its textured design is absolutely eye-catching. It’s both elegant and modern, and I’ve already received multiple compliments while wearing it. The Eco-Drive technology is a game changer — no more worrying about batteries. Plus, the atomic timekeeping is incredibly precise. It’s packed with features but still easy to read and operate. This watch feels like a piece of art on my wrist, and it’s now my go-to for both daily wear and special occasions. Highly recommended!”
