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.

Kobold Rattrapante Chronograph

Owners praise the Kobold Rattrapante Chronograph's high-contrast hands with luminous centers for excellent legibility on the white dial. One owner suggests a blue dial with polished steel subdials would offer a more interesting aesthetic. Overall, owners value the Kobold Rattrapante Chronograph for its legibility on the white dial.
