What people say

Owners + reviewers, side by side

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

Cincinnati Watch Company The Cincinnatus Blue

Owners widely praise the Cincinnati Watch Company The Cincinnatus Blue for its versatile design, pleasant manual winding action, and the value offered by its Sellita SW200-2 automatic movement, especially considering its USA assembly. The textured dial, often described as a "sandpaper dial" that shines in the sun, along with applied numerals and dark blue hands, are frequently highlighted as attractive features. Its 38mm or 39mm diameter and 47mm lug-to-lug dimensions are noted for good wearability on smaller wrists, though one owner found it necessary to remove four links for a proper fit. The lume is described as legible but dim. Overall, owners rate the Cincinnati Watch Company The Cincinnatus Blue highly for its distinctive dial and value at the 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.
