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.

Yema Superman Worldtime GMT

Owners widely praise the Yema Superman Worldtime GMT for its premium feel, unique bezel-lock mechanism, and attractive domed crystal. Some owners note the aluminum bezel insert is less desirable than ceramic and report the bracelet clasp can be stiff or difficult to open. Inconsistent quality control and poor customer service have been flagged by some owners. On balance, owners value the Yema Superman Worldtime GMT for its distinctive features and comfortable wearability.

From video reviewers

The "Coke" bezel and maxi dial are attractive design elements. The in-house automatic GMT movement is a French alternative to pricier GMTs.
