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.

Cincinnati Watch Company P-40 A-11 Pilot Black Automatic

Owners widely praise the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its sharp finishing, textured pearlescent dial, and excellent lume. The simple, understated design and comfortable 38mm size are also frequently highlighted. Some owners note the bracelet lacks quick micro-adjustments and the quick-release spring bars can dig into the wrist. One owner found the lume blocks potentially thinner and the font on larger numbers less desirable than a standard typeface, though the seconds hand was considered a success. Overall, owners highly recommend the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its great craftsmanship and value.
