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.

Zelos Nova 37

Owners widely praise the Zelos Nova 37's spectacular 37mm dimensions and extremely light, thin wearability. The meteorite dial is frequently highlighted as a captivating feature, though some reviewers suggest simpler indices would improve legibility over the Arabic numerals. The watch is considered a considerable value at $1,999. On balance, owners and reviewers rate the Zelos Nova 37 highly for its excellent dimensions and dial execution at the price.
