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.

Fortis Marinemaster M-44 DLC

The Fortis Marinemaster M-44 DLC is widely praised for its robust COSC-certified Kenissi Werk 11 movement, offering a 70-hour power reserve, and its stealthy, scratch-resistant Dianoir DLC coating. Owners find it comfortable to wear despite its 44mm size, with one owner considering it a standout piece. Some reviewers note a subtle difference in the color tone of the DLC coating on the crown and bezel lock between variants. Overall, owners and reviewers regard the Fortis Marinemaster M-44 DLC highly for its durable construction and reliable, high-spec movement.
