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 widely praise the Riley Watch Co Howard Hughes Chronograph - HH01 for its retro aviation aesthetic, delightful and quirky pastel color schemes, and nicely laid-out dials, with the color-matched NATO strap also noted as a standout feature. Some owners find the 12mm thickness to be a drawback, and one user dislikes the propeller-inspired logo. The watch utilizes a Seiko VK64 meca-quartz movement and has 50m water resistance. On balance, owners rate the Riley Watch Co Howard Hughes Chronograph - HH01 highly for its attractive aesthetic and colorways at its price point.
