Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Aquastar Benthos 500 II Founder s Edition is widely praised for its faithful reissue of an iconic dive watch, featuring a new monopusher chronograph movement with a unique central 60-minute display and improved wearability due to a slimmer case and redesigned lugs. Owners and reviewers highlight the comfortable 42mm case, the functional yacht timer, and the ease of use of the central chronograph for everyday timing. Some owners note that the 200m water resistance is a compromise from the original's 500m, and one reviewer flags the stamped clasp as a drawback at its price. Overall, owners and reviewers rate the Aquastar Benthos 500 II Founder s Edition highly for its unique chronograph function and comfortable, modernized vintage design.
The Aquastar Benthos Professional is widely praised for its significantly slimmer 13.9mm case, which contributes to comfortable everyday wear and a sleek profile, and its ultra-legible dial. Reviewers note its well-tensioned bezel and an improved beads-of-rice bracelet. Some find the 42mm case size substantial for a dive watch, and its 38-hour power reserve is considered unremarkable. The watch is priced at $1,290 during pre-order. Overall, owners and reviewers rate the Aquastar Benthos Professional highly for its comfortable wearability and legible dial at the price.
