What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Tsuki-yomi A-T

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.

Yema Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
