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.

Owners widely praise the Zelos Swordfish Field 38 for its comfortable dimensions, noting they are acceptable both on paper and in practice. The Seiko NH35 movement is highlighted for its exceptionally smooth winding feel. On balance, owners rate the Zelos Swordfish Field 38 highly for its value and comfortable wearability.
