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.

Geckota GT Racing Chronograph

The Geckota GT Racing strap is praised for its quality leather, crisp stitching, and beautiful patina, offering excellent value at less than half the price of similar vintage straps. Some owners find the 125/80mm length longer than ideal, and the keeper potentially smaller. On balance, owners rate the Geckota GT Racing strap highly for its quality and value, despite minor concerns about its length and keeper size.
