What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fears Brunswick 40.5 Jump Hour

Owners widely praise the Fears Brunswick 40.5 Jump Hour's stunning aventurine dial and vintage-modern aesthetic, with some noting excellent finishing. Reviewers highlight its fun dial visuals and unique in-house jump hour module. Owners are split on legibility with the jump hour complication, and some find the 12.8mm thickness substantial for some wrists. On balance, owners and reviewers rate the Fears Brunswick 40.5 Jump Hour highly for its unique dial and jump hour complication, despite some concerns about thickness and legibility.

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.
