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.

Horage Omnium K2

The Horage Omnium K2 is lauded for its slim 7.95mm profile and chronometer-certified K2 micro-rotor movement with a 72-hour power reserve. Reviewers note its technical innovation, including a proprietary silicon escapement and modular K1 movement, and praise its value. However, some find the molded, luminous hour numerals too whimsical, and the explicit mention of "silicon escapement" on the dial is considered unnecessary. On balance, reviewers rate the Horage Omnium K2 highly for its technical innovation and slim profile at its price point.
