What people say

Owners + reviewers, side by side

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

Baltic Scalegraph Classic

Owners widely praise the Baltic Scalegraph Classic for its stunning retro racing design, detailed dial, and 39.5mm case size, with many finding it offers excellent value. However, some owners report issues with finishing and fit, describing the watches as light or "toylike," while others find the finishing comparable to higher-end brands. Reviewers and owners alike criticize the screw-down chronograph pushers as finicky and impractical, especially given the 100m water resistance which some feel is conceptually incongruent with its rally timer purpose. One owner experienced misaligned bezel markers and moisture ingress after pool use, leading to a return. On balance, owners and reviewers value the Baltic Scalegraph Classic's aesthetic and value proposition, though practical usability concerns regarding the chronograph pushers and isolated quality control issues are noted.

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.
