What people say

Owners + reviewers, side by side

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

Christopher Ward The Twelve 660

Christopher Ward The Twelve 660 owners widely appreciate its thin 6.6mm case, achieved partly by reducing bezel and caseback diameters, and its well-made construction and value proposition. However, the community is split on the manual wind and lack of a second hand, with some finding these features unnecessary while others enjoy the interaction and thinness they enable. The bracelet's butterfly clasp lacks micro-adjustments, and some find the 30m water resistance limiting. Overall, owners and reviewers rate Christopher Ward The Twelve 660 highly for its innovative thin case design and perceived value, despite differing opinions on its manual-wind-only, no-date configuration.

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.
