What people say

Owners + reviewers, side by side

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

Citizen Atomic Perpetual A-T

Owners widely praise the Citizen Atomic Perpetual A-T for its handsome appearance, solid fit and finish, comfortable bracelet, and intuitive world time function. Its perpetual calendar and atomic timekeeping are highlighted as major conveniences, maintaining accuracy within 0.5 seconds even without syncing, and owners appreciate its "set & forget" nature and solar charging. The watch features a modest, stylish blue dial with delicate design details and a clutter-free layout, along with high water resistance without a screw-down crown and light titanium construction. Some find the dial unnecessarily busy, and its time zone functionality is noted as less useful outside the US, with atomic sync being less compelling below the equator. Accuracy is reported as +/-15 seconds per month if not syncing, but +/-0 seconds if it syncs via radio signal. Some find the watch a bit on the large side.

Yema Wristmaster Slim Small Seconds CMM.29

Owners widely praise the Yema Wristmaster Slim Small Seconds CMM.29 for its slim 9.5mm case, unique nature-inspired dial, and brushed steel finish. The micro-rotor movement is noted for its 4Hz beat rate and 42-hour power reserve, regulated to -/+ 10 seconds per day. Some owners report concerns regarding the movement and warranty process, while a reviewer questioned the value proposition at its price point and noted minor finishing inconsistencies on a prototype. On balance, the Yema Wristmaster Slim Small Seconds CMM.29 is highly regarded by owners for its distinctive design and comfortable wearability.
