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 deep red dial works in tandem with black accents and silver-tone touches for a display that’s as handsome as it is legible.\r\n\r\nIn 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 meters. Caliber H874.

“This is a gorgeous timepiece. I was looking for a functional watch with a moon phase. This watch works absolutely brilliantly, and looks amazing. It is also shockingly lightweight, making it comfortable for all day long wear.”

“The watch is pretty, the dial colors are not as vivid as product photos, but more subtle. Super light too.”

“Bought this watch in the red and blue moon phases. 1 for me and 1 for my dad. Off the bat ran into problems with the watch not functioning properly. Atomic receiver was broken or damaged wouldn't set the time. Citizen was great at taking care of this first problem. Second issue is the pins used to connect the metal links. Had one fall out and my watch fell apart while out at a bar. Thankfully I caught it before it dropped face first. This I have not addressed as the time to get this fixed would be extremely long. I recommend everyone check their watch thoroughly. beautiful watch but craftsman ship is lacking it seems. My Citizen Nighthawk which is half the price is much better and has held up for years.”

“After wearing the Citizen Tsuki-yomi A-T [BY1018-55X] for nearly six months, I can confidently say it has become one of the highlights of my collection. The moment it came out of the box, the complimentary bracelet sizing made the experience feel effortlessly premium. It fit perfectly upon first wear, and that alone set the tone for everything that followed. The case size is spot on, substantial without being bulky, refined without feeling delicate. On the wrist it strikes the exact balance I look for: presence without shouting for attention. And the dial? It is even better in person. The moonphase display paired with the subtle color contrasts gives the watch an elegance that feels both modern and timeless. Eco-Drive continues to impress me. I never have to think about power; it just runs. And when it comes to accuracy, the radio-controlled timekeeping is nothing short of exceptional. Knowing the watch is always synced and precise adds a level of confidence that is hard to match. My only real gripe is the black enamel on the bezel. It scratched far more easily than expected, and I honestly do not even know when it happened. It was a surprise given how well the rest of the watch has held up. That said, it has not taken anything away from the overall beauty. The watch still looks stunning, and the scratch blends in more than I would have expected. Overall, the Tsuki-yomi A-T has been a joy to wear. It is reliable, beautiful, comfortable, and technically impressive in a way that never feels gimmicky. Even with that one cosmetic hiccup, I am still genuinely pleased with it, enough that I catch myself admiring it more often than I would like to admit.”
