Reviews

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

Casio EFB-730D

Owners widely praise the Casio EFB-730D for its 40mm size, which is considered perfect for smaller to medium wrists and versatile for strap changes with its 20mm lug width. The subtle sunburst blue dial is noted as classy and better in person than in photos, and the overall finish is considered quite good for the price. Some owners find the constantly running central seconds hand impractical, while others appreciate its straightforward Casio quartz reliability and value around $150. One owner reported the second hand sticking on the minute hand, and another found the 47mm lug-to-lug measurement wore larger than expected. Overall, owners rate the Casio EFB-730D highly for its comfortable wearability and attractive design at the price point.

Brew Metric

Brew Metric owners and reviewers praise its 1970s-inspired 36mm TV case design, with some finding its proportions satisfying on a 7-inch wrist and its 10.75mm to 10.8mm thickness comfortable. The dial is frequently lauded for its depth, textured indices, sunken subdials, and pleasing retro colorways, while the bracelet is noted for its dramatic taper and ability to mimic an integrated look. The VK68 meca-quartz movement's running seconds accurately hit all markers. However, some owners report quality control issues, including dial spots or missing lume, and one user found the bezel dented easily. The lug width is noted as 19.85mm, limiting strap compatibility, and the watch lacks lume. Opinions are split on how the 36mm case wears, with some finding it wears larger due to bracelet integration, while others praise its compact wearability. Overall, owners and reviewers rate the Brew Metric highly for its distinctive retro design and comfortable wearability at its price point.

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.
