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 Olmsted ExP-01

Owners widely praise Oak & Oscar The Olmsted ExP-01 for its exceptional finishing, comfortable bracelet, and smooth movement. The dial designs are a frequent point of admiration, with specific appreciation for the white, navy, and gray variants, as well as the orange seconds hand. The watch is considered fairly priced at around $1.5k and is noted for its versatility and "soul." On balance, owners rate Oak & Oscar The Olmsted ExP-01 highly for its overall quality, design, and the brand's customer service.

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.
