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 40 (Ti)

Christopher Ward The Twelve 40 (Ti) owners and reviewers highlight its high value, comfortable and lightweight titanium case, and COSC-certified Sellita SW300-1 movement. Some owners praise the finishing and textured dial, with one noting the sharpness of bracelet links is by design. However, a recurring point of criticism is the sharp edges on the bracelet links, with some also finding the inside surfaces of the clasp unfinished. One owner felt the dial appeared cheap for the price, while a reviewer desired more design originality in the dial and a micro-adjust system for the bracelet. Overall, owners and reviewers rate Christopher Ward The Twelve 40 (Ti) highly for its value and comfortable titanium build, despite some reservations about bracelet finishing and dial design originality.

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.
