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.

Marathon Steel Navigator SSNAV Auto

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
