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.

KUOE ROYAL SMITH 90-006

Owners widely praise the KUOE ROYAL SMITH 90-006 for its visual appeal and sapphire crystal with AR coating. The watch functions correctly and keeps time at approximately +5 seconds per day on the wrist, powered by a Miyota 9039 movement. On balance, owners value the watch's aesthetics and specifications, though some question its overall value proposition.

From video reviewers

The watch's unique blend of modern and retro elements is a notable strength, with a textured ivory waffle dial and Breguet numerals giving it the look of a vintage watch from the 1950s and 1960s. A potential drawback is the ~$770 USD price point, which is significant for a microbrand. Reviewers disagree on the movement's accuracy, with one reviewer noting it is noisy and another describing it as a "Japanese-manufactured high beat premium automatic movement".
