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.
The Sternglas Tachymeter is praised for its sporty chronograph design and wrist presence, offering character without being an overt tool watch. Reviewers note an upscale design with a colored aluminum bezel insert and more colorful dial options compared to its predecessor. The watch is considered good value for its design, functionality, and small-brand cachet, with a charming youthfulness in its colorful dial options. One reviewer points out that the "orange" on one model appears yellow and suggests a tachymeter scale extending to 200 would be more useful than the current 500. Overall, owners and reviewers rate the Sternglas Tachymeter highly for its competitive price and appealing, youthful design.
The value at the moderate price point is a strength. The use of a meca-quartz movement is a weakness. Reviewers disagree on whether the meca-quartz movement is a drawback.
