Bremont Williams RacingvsYema Skin Diver CMM.20

The Bremont Williams Racing features a panda dial with blue accents and a tachymeter bezel, housed in a 43mm TripTick case. It is powered by a chronometer-rated BE-53AE automatic movement with a 42-hour power reserve and a custom rotor. While the 15.8mm height is considered reasonable for a chronograph, the 43mm case size may require trying it on for those preferring smaller watches. Overall, reviewers highlight the motorsport-inspired design and robust build of the Bremont Williams Racing.

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.
