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.

Yema Navygraf Chrono

Owners praise the Yema Navygraf Chrono for its handsome, versatile design and the value offered by its Valjoux 7750 movement. A reviewer notes the 40mm case's fully polished finish, which some feel clashes with its sporty aesthetic, and mentions its 13.9mm thickness is noticeable. One owner reported wearing the Yema Navygraf Chrono for two months without issues, receiving compliments. On balance, owners and reviewers find the Yema Navygraf Chrono to be a good-looking and well-specced watch for its price.
