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 GT

The Zelos GT is lauded for its value and bold design, with owners highlighting the cool power reserve meter and superb 3-point micro-adjust bracelet. Some owners find the case and lugs could hug the wrist better, and the bracelet is noted as being quite long, requiring significant link removal for a 7.1-inch wrist. The dark green dial, while inspired by Lamborghini, is described as appearing mostly black. Overall, owners rate the Zelos GT highly for its value and the quality of its bracelet at the price point.
