Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Aquastar Benthos 500 II Founder s Edition

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.

Marathon GSAR (Government Search & Rescue) Diver's Automatic

Overall, owners and reviewers rate the Marathon GSAR (Government Search & Rescue) Diver's Automatic highly for its robust build and constant legibility from tritium.
