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 C1 Bel Canto

The Christopher Ward C1 Bel Canto is praised for its three-dimensional, futuristic aesthetic and exposed chiming mechanism, with its design language compared to MB&F. Reviewers note the Cielo blue dial's transition from pale blue to grey and the hand-finished anglage on the sonnerie au passage complication's levers and hammers. The 41mm grade-5 titanium case is finished with fine brushing, and the movement is a Sellita SW200-1 base with an FS01 chiming module, offering a 38-hour power reserve. One reviewer found the Oyster-style bracelet stylistically mismatched with the classical dial of the C1 Bel Canto Classic. Overall, reviewers highlight the C1 Bel Canto's striking design and intricate chiming complication as its primary appeal.

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.
