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.

“The Tsuki-yomi A-T BY1018-55X watch is a nice watch, which keeps excellent time. My location does not always receive a strong radio signal from Colorado for the atomic time setting. All the watch configurations work well. The only issues I have are I'd like to see the date window larger or a date crystal magnifier. maybe this can't be done with sapphire crystals. Second the luminescent material on the minute and hour hands and the fixed hour luminosity indicators are very weak. I read my watch in low light often and there is no luminosity so I can't read the dial even after being in strong light, The luminosity fades quickly. I suggest that a new luminosity material be applied or use tritium. This is a mid-range priced watch. Don't skimp on the price of a quality luminosity material that lasts after exposure to light. If tritium is used the luminosity will last 24 hours a day for a half live of about 12+ years.”

“Really neat awesome watch Easy setup 1.check time zone & adjust 2.check atomic clock make sure 9 o’clock is toward Boulder, COyou can force the watch to sync with atomic clock see instructions ez to do. 3. Check hemisphere N or S & set 4 check to make sure you watch is communicating with boulder. Once it syncs with Boulder Atomic Clock, the watch time, date, moon settings will be perfect if it communicates with the Atomic clock. Watch a video on you tube or download instructions it takes about 15 minutes using video. Absolutely stunning watch”

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