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 Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
