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 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.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
