Is the Tsuki-yomi A-T worth it?

For a titanium moonphase with sapphire and solar atomic timekeeping, $850 at Watch Warehouse as of November 3 is a fair price. Comparable moonphase watches from Swiss brands usually cost far more.

Does it need a battery?

No. The Eco-Drive solar cell charges from light and powers the quartz movement, so there is no battery to replace.

How does the moonphase work?

The moonphase display tracks the lunar cycle and is kept in sync by the radio-controlled module. It does not need manual resetting after each full moon.

Will the atomic timekeeping work where I live?

It depends on distance from the radio transmitters used for your region. In weak-signal areas it still runs as a normal quartz watch and can be set manually.

Expect the watch, a titanium bracelet, and Citizen's manual and warranty card. Check the listing for the exact included items.

Our take on the Citizen Men's Tsuki-yomi A-T Watch

The Citizen Tsuki-yomi A-T is a titanium moonphase watch that runs on Citizen's Eco-Drive solar quartz movement, so it never needs a battery change. Its standout feature is a moonphase display driven by a radio-controlled atomic timekeeping module, which sets itself automatically from time signals. It uses a sapphire crystal and a lightweight titanium case, which is unusual at this price. The latest best price is $850 at Watch Warehouse as of November 3.
