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 Union Terminal Mechanical

Owners praise the Cincinnati Watch Company Union Terminal Mechanical for its striking design and historical significance, particularly for Cincinnati natives. One owner highlights its suitability as a dress watch, finding it wears well on a leather strap. The watch is noted for its colors and design inspired by the Union Terminal clock, with a portion of sales supporting the landmark. At just over $350, it is considered a good value despite not featuring a high-end movement, strap, or crystal. Overall, owners rate the Cincinnati Watch Company Union Terminal Mechanical highly for its unique design and local historical connection at an accessible 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.
