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 Pearl Diver Nessie

Owners widely report a split on the Spinnaker Fleuss Pearl Diver Nessie's build quality, with some finding it disappointing due to issues like misaligned bezels or indices, while others praise its robust construction. The watch features a blue mother-of-pearl dial with a hidden Nessie silhouette, powered by a Miyota 8245 movement and priced at $425. One owner noted the Spinnaker Fleuss Pearl Diver Nessie felt a bit large. Overall, owners and reviewers find the Spinnaker Fleuss Pearl Diver Nessie offers good value with unique design elements that celebrate its theme without being overly cartoonish.

From video reviewers

The blue Mother-of-Pearl dial with "Nessie" easter eggs is a distinctive design element. The 43mm case size may be substantial for smaller wrists.
