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.

Overall, owners rate the Makydo Sapphire Thunder Blue 42 highly for its elegant and sporty aesthetic at the price point.
