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.

Sinn U18

The Sinn U18 is praised for its unique deep blue/green dial with three-dimensional oxygen bubbles that change with light, and its comfortable, easily adjustable bracelet. Owners find the watch stunning and a piece of history, appreciating the refined hands. The Sinn U18 features a 44mm, 15.5mm thick case made from German submarine steel, offering a 2000-meter dive specification and Sinn's Ar-Dehumidifying technology, powered by a Sellita SW300-1 movement. The case thickness is apparent, and the watch comes as a complete set with box and papers for $3,000-$3,680. On balance, owners and reviewers rate the Sinn U18 highly for its striking dial and robust build.
