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.

Seestern S450 Ocean Star

Owners widely praise the Seestern S450 Ocean Star's Yachtmaster-style case and flawless bracelet finishing, with one owner noting the ST2130 movement keeps good time. The bezel action is described as having individual notches but feeling like a friction bezel, while another owner flags the bezel and crown action as smooth with perfect alignment. Lume is a point of contention, with one source describing it as a nice cool blue with ice-white application, while others note it as weak or not matching Prospex standards, despite using BGW-9. The watch is considered a "big boy" ideal for larger wrists (19cm+), potentially too large for 17cm wrists due to its size and non-tapering bracelet. Overall, owners rate the Seestern S450 Ocean Star highly for its build quality and finishing at the price point, despite some reservations about its size and lume intensity.
