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 and reviewers highlight its exceptionally thin 6.6mm case, achieved through a two-hand design, manual-wind movement, and 30m water resistance. The bracelet clasp, however, lacks micro-adjustments. Opinions are divided on the manual-wind nature and absence of a seconds hand, with some finding them unnecessary while others value the resulting slimness and winding experience. One user noted the logo as a drawback. Overall, the Christopher Ward The Twelve 660 is considered good value and well-made by the community, with its thinness being a primary draw.

Yema Superman Worldtime GMT

Owners widely praise the Yema Superman Worldtime GMT for its premium feel, unique bezel-lock mechanism, and attractive domed crystal. Some owners note the aluminum bezel insert is less desirable than ceramic and report the bracelet clasp can be stiff or difficult to open. Inconsistent quality control and poor customer service have been flagged by some owners. On balance, owners value the Yema Superman Worldtime GMT for its distinctive features and comfortable wearability.

From video reviewers

The "Coke" bezel and maxi dial are attractive design elements. The in-house automatic GMT movement is a French alternative to pricier GMTs.
