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.

Knot Watches CC-39MRGOW

Knot Watches CC-39MRGOW owners widely praise its attractive display and Bauhaus-style design, with one owner noting the cream dial and orange second hand as a particular highlight. The watch is also appreciated for its light weight and affordability, with one owner calling it a well-made, Made in Japan souvenir. However, some owners report issues with the strap and clasp quality, and one experienced poorly executed engraving. The narrow strap width, specifically a non-standard 17.9mm lug width, is a recurring point of contention, preventing the use of standard 18mm straps, and the need to send the watch to Japan for battery changes is seen as an inconvenience. Overall, owners appreciate the Knot Watches CC-39MRGOW for its unique aesthetic and value, despite some reservations about strap quality and servicing.
