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.

Undone ur

Owners report satisfaction with the quality for the money and praise the well-finished 40mm steel case with excellent polishing for the price. Reviewers highlight the Seiko VK61 meca-quartz movement, noting the pushers feel mechanical and hands reset properly, and appreciate the impressive strap quality and customization options. Some owners report receiving units that are not working. The mineral crystal causes glare, hindering dial visibility. Overall, owners and reviewers rate the Undone ur highly for its value and customization options, offering a high-end feel for the price.
