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.

Spinnaker Fleuss GMT

Owners widely praise the Spinnaker Fleuss GMT for its aesthetic appeal, comfortable and light wearability, and value, especially when discounted. The textured blue dial, applied lumed markers, and sapphire crystal with AR coating are highlighted as stunning features. Owners also note the dial is very well lumed and the bracelet has helpful quick-release tabs. However, the 43.3mm case size is criticized by some as being too large, and the Beads of Rice bracelet is described as "jingly jangly" with a pressed clasp and a clasp that isn't finely finished. Some users flag the internal bezel rotates too easily. Overall, owners rate the Spinnaker Fleuss GMT highly for its aesthetic success and value at its affordable price point.
