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.

Grand Seiko SBGR321

Grand Seiko SBGR321 owners and reviewers widely praise its attractive design, compelling dimensions, and robust movement. The watch features sharp case lines with contrasting brushing and polishing, a 40mm steel case that provides presence without bulk, and 100m water resistance. Its sunburst blue dial, inspired by the dawn sky over Mount Iwate, showcases Grand Seiko's signature finishing on applied markers and hands, with a red-tipped seconds hand. The 9S65 automatic movement is noted for its precision, running within specifications, with one source reporting a +5 to -3 seconds a day rate and a 3-day power reserve. A blue rotor with a crimson rim, also inspired by Mount Iwate, is visible through the display caseback. On balance, owners and reviewers rate the Grand Seiko SBGR321 highly for its exceptional finishing and compelling blue dial design at its price point.
