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 Twelve X (Ti)

The Christopher Ward Twelve X (Ti) is praised for its exceptionally finished, lightweight titanium case and COSC-certified, skeletonized SH21 movement offering a 120-hour power reserve. Reviewers note its comfortable wearability due to the rounded case shape, despite a 12.3mm thickness, and highlight the micro-adjust clasp. Legibility is considered good for a skeletonized watch, though reduced compared to standard dials. One reviewer points out that the case chamfers may be prone to dings and the movement finishing does not reach higher-end standards. Overall, reviewers rate the Christopher Ward Twelve X (Ti) highly for its impressive case finishing and the value of its COSC-certified, in-house skeletonized movement.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
