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.

Studio Underd0g Guacamole (Gen3)

Owners widely praise the Studio Underd0g Guacamole (Gen3) for its fun, cheerful, and unusual design with great colors, and one owner found its actual wrist presence perfect. Some owners, however, find the dial printing tacky and the overall design looking cheap, while others feel it is a bit pricey for what is offered. The pushers lack crispness, and the crystal is very reflective and domed too much at the edges. One owner expresses concern that it uses a Seagull ST91-B movement, known for a high failure rate. On balance, owners are split on the value proposition of the Studio Underd0g Guacamole (Gen3) at its current price point, with some appreciating its unique aesthetic and others finding the design and movement choices underwhelming.
