What people say

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

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.

Oak & Oscar The Humboldt 12-hr

Oak & Oscar The Humboldt 12-hr owners widely praise its comfortable, solid bracelet with screw links and tight end-link fit, along with its awesome sandwich dial featuring superb grain and crisp details. The 12-hour bezel is noted as excellent for tracking a second time zone, and the orange second hand adds a nice pop. One owner reports the watch has outstanding quality and a perfect fit on smaller wrists, while another notes its legibility and great presence on various straps. A reviewer describes it as a 40mm stainless steel tool watch with a matte, brushed finish and a sandwich dial, powered by an ETA 2892-A2 movement with a 42-hour power reserve. Some in the line report the lume could be brighter. On balance, owners and reviewers rate Oak & Oscar The Humboldt 12-hr highly for its build quality and versatile tool-watch design.
