Product description
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.

Ever since CITIZEN was founded in 1930, the company has cultivated a multicultural mindset that has consistently produced excellence and creativity. The long history of watchmaking includes product innovations such as radio and satellite-synchronised timekeeping. Another revolutionary breakthrough was the development of the light-driven Eco-Drive technology. Eco-Drive is Citizen's patent-protected technology that uses any natural or artificial light source to power the watches. The solar cell integrated in the watch captures light and converts it into energy. Additional electrical energy is stored in a rechargeable battery.
We are an authorised specialist and online retailer of the Citizen brand, which has decisive advantages for you as a customer in terms of security, warranty and after-sales service when purchasing online.
- I gave this watch to my husband, and he fell in love with it the moment he put it on his wrist. (Translated automatically with Google™ View original text)
- The Super Titanium™ case is lightweight yet robust, and the mix of silver, black and anthracite accents creates a sophisticated and modern look. The dial with the moon phase display is particularly fascinating, a detail that immediately catches the eye. This is more than just a watch, it is a true technological gem. My husband loves the precision of the atomic timekeeping and the display of the 24 time zones, which are perfect for his travels. The perpetual calendar is another practical feature, as is the Eco-Drive technology, which eliminates the need to change the battery. Despite its many features, the watch remains incredibly light and comfortable to wear all day. The 43 mm size is ideal, neither too bulky nor too discreet, and it fits perfectly with his style. This gift was a total success! This watch is a perfect blend of technology, elegance and practicality. My husband is delighted, and I am happy to have found such an exceptional gift. I highly recommend this watch to anyone who wants to combine performance with refined design. (Posted on 01.12.2024)
- Technical masterpiece (Translated automatically with Google™ View original text)
- The technical 'miracle' is actually less bright in real life, but rather in a subtle silver-anthracite - excellent! The (complex) watch is very comfortable to wear thanks to 'super titanium'. Be sure to consult the attached link for the 11-page (!) and easy-to-read instructions for use. This world's first light-operated and radio-controlled watch with a correct moon phase display is a novelty - automatic world time settings - hands move automatically forwards and backwards as if by magic. Perpetual calendar controlled by an atomic clock - the annoying change from summer/winter time is automatic, as is the change from months with 30/31 days to the 1st of the following month. Every watch collector knows this: manual date adjustment and time setting - if necessary - is unnecessary here. The price invested is definitely worth it. Highly recommended, you won't find all these (technical) functions (yet) in other brands. I (Posted on 17.09.2024)
- Gorgeous (Translated automatically with Google™ View original text)
- Ordered on December 26 after Christmas, I was expecting delivery from January 15 after the recovery..but at Christian they are always excellent, delivered on January 11!! First class service. The watch is splendid, very well made and it's the first time I've seen a solar-recharged watch, with atomic time (radio controlled) on which we have... the moon phase, the power reserve , the perpetual calendar and the worldtimer with, on the back, 24 time zones, automatic time zone adjustment if you move or manual, simply by pulling out the crown. In addition, an ultra-light titanium case that you almost don't feel when you wear it. Flawless from Citizen, a stunning watch and of course exceptional service from Christian. Well done (Posted on 15.01.2024)
- Stunning (Translated automatically with Google™ View original text)
- What can we say about this watch except that it is a marvel. To start with, titanium is super light and the finishes of the case and bracelet are perfect. The dial is superbly worked with the moon in the background there is a lot of relief index applied even the moon in the dial makes this one has details painted on it a splendor. As for the functions, it's great, the watch adjusts itself, you just have to put it on the correct time network and you no longer need to touch it. I took the bloodmoon version which to my taste is the most beautiful. Thank you very much Citizen for this beauty. (Posted on 21.12.2023)
- Splendid (Translated automatically with Google™ View original text)
- Moon phase, solar drive, titanium and radio-controlled punctuality. At such a price. Simply great. The only thing I have a slight complaint about is that it could be 2-3 mm larger in diameter. But that's peanuts. (Posted on 12.02.2025)
- Magnificent. This watch is a visual and technical masterpiece. Simply magnificent. (Translated automatically with Google™ View original text)
- I am very satisfied from start to finish. Service, performance, customer service as always top notch. The watch I bought is very great and a visual eye-catcher (Posted on 03.02.2025)
- Amazing watch (Translated automatically with Google™ View original text)
- Very beautiful watch with cutting-edge technology, and magnificent moon phase (Posted on 10.06.2024)
- Very nice (Translated automatically with Google™ View original text)
- Very nice watch, with so many functions. Even more beautiful live (Posted on 14.11.2023)

Questions about warranty
How long is my warranty?
You will find details of the item's warranty on the relevant product page under additional information. We provide the official international manufacturer's warranty for branded watches and branded jewellery. This is at least 24 months. Individual brands or products sometimes have a significantly longer warranty. CHRISTIAN brand jewellery is guaranteed for 24 months.
What does the warranty cover?
A watch's warranty generally covers manufacturing and material defects, including the movement, hands, dial, crown and sometimes the case. However, it does not cover damage resulting from incorrect use, lack of care (see our maintenance tips), accidents or normal wear and tear (e.g. straps, batteries, etc.).
Questions about the products
Are your watches original?
Yes, all the products we sell are original and 100% new. They are purchased directly from the respective manufacturer.
Is the watch water-resistant?
Information on water resistance is indicated for each watch in the product information. Here you can find the detailed meaning of the various specifications and the water activities you can do with your watch: www.uhrenschmuck24.ch/wasserdichtigkeit
What is the difference in colour between 14-carat and 18-carat gold?
18 carat gold contains 75% pure gold, which gives it an intense, warm yellow colour that radiates elegance. In comparison, 14 carat gold, with 58.5% pure gold, has a slightly lighter, more restrained yellow colour. In white gold, 14 carat appears brighter and more radiant, while 18 carat has a softer, subtle lustre. In rose gold, 14 carat stands out with a more intense shade of pink, while 18 carat is characterised by a softer, more restrained shade of red.
Does the jewellery come with a certificate of authenticity?
All CHRISTIAN diamond jewellery is sent with a certificate of authenticity indicating that our diamonds are natural and extracted from conflict-free sources. CHRISTIAN gold jewellery and silver jewellery do not come with a certificate. The responsibility label (CGZ stamp) on the piece of jewellery is sufficient to indicate that it was produced by CHRISTIAN AG. The gold quality is indicated by the symbol 750 or 585. The silver quality is indicated by the symbol 925.
Are your diamonds and gemstones natural?
CHRISTIAN diamonds and gemstones are natural. They come from conflict-free sources and meet the strictest international standards.
