What people say

Owners + reviewers, side by side

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

Eone Relay Bradley

The Eone Relay Bradley is widely praised for its unique, tactile time-telling design and lightweight titanium case. Owners and reviewers highlight its innovative magnetic ball bearing system as a conversation starter and a reliable way to tell time in the dark. However, some users report that the ball bearings can be dislodged or hang after a battery change, and opinions on its value at the $285 price point are mixed. One owner suggests avoiding full retail. More size and color options would be desirable. Overall, owners and reviewers rate the Eone Relay Bradley highly for its ingenious, accessible design and comfortable wearability.

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.
