What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.

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.
