What people say

Owners + reviewers, side by side

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

Nodus Duality II

Owners widely praise the Nodus Duality II for its refined dial construction, improved proportions, and wearability with a thinner 11.5mm case. The dual-crown functionality for movement and internal rotating bezel is a key feature, alongside 300 meters of water resistance and a durable three-link bracelet with the NodeX extension. The Miyota Cal. 9015 movement is noted, with some owners preferring Nodus finishing over alternatives. One owner finds the Nodus Duality II overpriced at $868, citing a loud rotor and lower-quality bracelet, while others argue US assembly, the movement, and the internal bezel justify the cost. On balance, owners and reviewers rate the Nodus Duality II highly for its refined design and wearability at its price point.

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.
