What people say

Owners + reviewers, side by side

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

Nodus Sector II Sport

Owners widely praise the Nodus Sector II Sport for its comfortable 38mm wearability, unique three-level sector dial with applied indices, and thin case. Accuracy varies, with one owner reporting plus 4 seconds per day. Criticisms include a bulky clasp with sharp edges, a strong blue AR coating, and the non-reversible bronze bezel patina. The use of an NH38 movement in a watch priced over $500 is also noted. Overall, owners rate the Nodus Sector II Sport highly for its comfortable wearability and unique dial design.

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.
