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. 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 meters. Caliber H874.

“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.”

“Very attractive watch. Men don't worry about the purple face being too much. It is very understated and masculine. I have four Citizen watches and have owned others additionally that I have gifted to my sons. This is my favorite. I was at church and a couple, two rows behind me, noticed it on my wrist and came up and ask me about it.”

“I’m beyond impressed by this watch. Citizen shipped it extremely quickly and handled sizing the band very fast as well. The watch was delivered set to my time zone and ready to go out of the box which is perfect because I was scared of the setup from online reviews. The accuracy is almost perfect (compared to the iPhones clock) down to around half a second or so and the moon phase matches what’s in the sky. It’s crazy to me because I’ve never owned a watch like this before but it’s exactly as advertised. The watch also looks fantastic. I wear it to work but it’s very dressy and can be worn to any special occasion. The red dial is beautiful and the titanium is a nice looking darker metallic color. Would buy again”

“I really love this watch. It fits perfectly and looks stylish on my wrist. The color of the dial is stunning. I also love the fact that I don’t have to set it as it is radio controlled, so it’s on time whenever I wear it. It doesn’t need to be wound as any light source powers it. I highly recommend this watch.”
