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

The Fortis Marinemaster M-44 is praised for its excellent build quality and wearability, featuring a highly legible dial and a COSC-certified Kenissi-based movement that ran at 0 seconds per day. Owners appreciate its 70-hour power reserve and the inclusion of multiple straps and a deployant buckle, noting its gorgeous appearance and great wrist presence. A minor point raised is the 21mm lug width, with a wish for it to be 22mm. The Fortis Marinemaster M-44 is priced at $4,150. Overall, owners and reviewers rate the Fortis Marinemaster M-44 highly for its robust specifications and comfortable wearability at its price point.
