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.

The watch has a problem with the alarm.
Color: Black/Black/Digital, Color: Black/Black/Digital
This is perhaps the nicest digital watch I’ve ever had, the watch is new, but it came broken, the alarm does not sound or better to say sounds so low, it is inaudible, is practically useless, do not know if it can be fixed, I’ll have to take you to a technician, the problem is that I am in Ecuador, I do not know if the guarantee will serve or can be returned. ------------------------- Este es quizás el reloj digital más bonito que he tenido, el reloj es nuevo, pero me vino averiado, la alarma no suena o mejor dicho suena tan bajo, es inaudible, es prácticamente inservible, no sé si se pueda arreglar, voy a tener que llevarle a un técnico, el problema es que estoy en Ecuador, no sé si sirva la garantía o se pueda devolver.

Love it!
Color: Light Blue
Great summertime watch. Wore it all the time. I resized it much smaller, but easy enough to do. Completely waterproof. Would buy again...and did in grey for the winter. Highly recommend.
