Aquastar Deepstar ChronographvsCasio EFB-730D

Owners widely praise the Aquastar Deepstar Chronograph for its excellent finishing, historical appeal as a faithful 1960s tool watch recreation, and its smooth column wheel chronograph action, with some noting it surpasses competitors. Reviewers and owners alike highlight the 39mm case size as a significant improvement in wearability, though its 14.8mm to 17mm thickness is noted as substantial. The watch features a sapphire crystal with triple AR coating for excellent legibility and 200m water resistance. Some owners express a preference for a bracelet option over the included tropic and leather straps, and one reviewer found the 21mm lug width awkward. Overall, owners and reviewers rate the Aquastar Deepstar Chronograph highly for its authentic vintage tool watch character and impressive build quality at its price point.

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.
