The community take
Owners talk.
The Citizen Tsuki-yomi A-T is widely praised for its gorgeous, detailed moonphase complication, available in gray, blue, or red, and its visually light Super Titanium case. Reviewers and owners alike highlight the comfortable wearability offered by the 43mm case, which is 11mm thick with short lugs and features a mix of brushed and polished finishes. The radio-controlled atomic timekeeping and Eco-Drive movement are noted as key features, along with a world time zone guide on the case back. Some users find the pushers and crown for setting time zones and hemisphere settings, along with the chapter ring functions, to be unintuitive. On balance, owners and reviewers rate the Citizen Tsuki-yomi A-T highly for its striking moonphase display and comfortable, lightweight titanium construction at a great price.
