What people say

Owners + reviewers, side by side

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

Brew Metric

The Brew Metric is widely praised for its 1970s-inspired retro design, with reviewers and owners specifically highlighting its unique dial aesthetics, compact 36mm case size, and comfortable wearability on various wrist sizes. The watch's finishing is frequently lauded, with particular appreciation for its contrasting brushed and polished surfaces and well-executed gold treatment. Owners also note the pleasing feel of the pushers and crown, the accuracy of the VK68 meca-quartz movement, and the sapphire crystal. However, some owners report quality control issues, including dial defects and missing lume, and a few find the bezel dents easily. The bracelet is a point of contention, with some finding it uncomfortable and prone to pulling arm hairs, while others praise its dramatic taper. The watch's 50-meter water resistance is considered cautious by one reviewer, and the lug width of 19.85mm limits strap options.

From video reviewers

The watch's unique design and compact dimensions are praised. The bracelet is noted as stiff and lacking flexibility. Reviewers were divided on whether the Seiko NH35A movement or the meca-quartz movement offered better value at the price point.

Yema Wristmaster Slim CMM.20

The Yema Wristmaster Slim CMM.20 is widely praised for its compelling integrated bracelet design and comfortable 39mm wearability. Reviewers highlight its impressive value, featuring an in-house CMM.20 micro-rotor movement with a 70-hour power reserve, adjusted to -3/+7 seconds per day, all within a slim 9mm case. Some note the domed sapphire crystal can produce glare and the dial text is quite small. On balance, reviewers rate the Yema Wristmaster Slim CMM.20 highly for its integrated design and value proposition with a micro-rotor movement.
