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.

Dryden Chrono Diver Gen 2

Owners widely praise the Dryden Chrono Diver Gen 2 for its exceptional value and comfortable wearability, with many appreciating the PVD finish. Reviewers note its vintage-inspired design, improved lume, and solid bezel action. The 42mm case and 49mm lug-to-lug measurement are considered by some to be large for smaller wrists. Overall, owners and reviewers rate the Dryden Chrono Diver Gen 2 highly for its impressive value and refined features at its price point.

From video reviewers

The fully lumed steel bezel insert is a significant strength. The bracelet is a notable upgrade from the previous generation. Reviewers did not agree on any specific weaknesses.
