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 40 Automatic

Owners find the Spinnaker Fleuss 40 Automatic a good size for smaller wrists, though one owner notes the lume is too diffuse for easy nighttime reading. The pilot-style crown is an unusual feature for a dive watch. Overall, owners value the Spinnaker Fleuss 40 Automatic for its wearability on smaller wrists.

From video reviewers

The coral red dial is a unique aesthetic. The watch is a strong contender for best-in-class under $300.
