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.

Lorier Zephyr

Owners widely praise the Lorier Zephyr for its stunning guilloche-style dial, refined and perfectly sized unique case shape, and comfortable wearability. The Miyota 9 series movement is noted by owners as being a little noisy, with a rotor whirring audible on quick hand movements. On balance, owners rate the Lorier Zephyr highly for its distinctive dial and case design at the price.

From video reviewers

The watch's vintage aesthetic and value for money are praised. The bracelet's refinement and perceived rattle are noted as a drawback.
