What people say

Owners + reviewers, side by side

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

Brew Super Metric

Owners widely praise the Brew Super Metric's unique, asymmetrical, and colorful 70s-inspired design, with many appreciating its finishing and dial details for the price. Some owners find the integrated bracelet can be a hair-puller, and the watch wears larger than its 36mm dimensions due to the square case and bracelet. The lume is noted as weak, and some find the dial graphics busy, though others love the colorful, essence-keeping 2.0 design. On balance, owners rate the Brew Super Metric highly for its distinctive style and value, with many finding it a fun and comfortable daily wearer.

From video reviewers

The Brew Super Metric's Meca-Quartz Chrono functionality is one of the best the reviewer has seen. The watch's unique design is a key part of its charm. The Seiko meca-quartz caliber contributes to its value for the price. The lume could be improved, as it's not as bright as some other watches in its class. The price may not be the cheapest option in its class.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.
