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.

Hamilton Khaki Field Pioneer Automatique

Owners widely report the bracelet quality is a notable drawback for the price, and some find the dial basic and lacking legibility due to the absence of AR coating. However, the Hamilton Khaki Field Pioneer Automatique is praised for its accurate movement featuring an 80-hour power reserve, and its lug-to-lug dimension is noted as near-perfect for smaller wrists. The inclusion of a 24-hour scale is appreciated. Overall, owners find the Hamilton Khaki Field Pioneer Automatique to be just okay for its asking price new, with the movement's performance being a key positive aspect.
