Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners praise Straton's customer service and the unique horizontal brushed dial on the Volante, with one owner noting the BGW9 lume on thin hands is surprisingly good. The 38mm size is recommended for wrists smaller than 7 1/4 inches. Some owners report the meca-quartz movement is not very precise, and one owner experienced a band that was too short with no response from customer service. Overall, owners appreciate the Straton Sportiva and Volante for its distinctive dial and comfortable bracelet, despite some reservations about the meca-quartz movement's precision.
