Reviews

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

Aquastar Benthos 500 II

The Aquastar Benthos 500 II is widely praised for its wearability, with reviewers and owners noting its comfortable 42mm case and improved ergonomics over the original, making it easy to wear even on smaller wrists. Its unique monopusher chronograph function, operated by a 2 o'clock pusher, is highlighted as exceptionally useful for everyday timing and racing. The watch features a bespoke automatic Aquastar 1MPS movement and is noted for its quality finishing and attractive price for its heritage and unique complications. However, some sources point out that the "500" in the name is misleading given its 200m water resistance, and the stamped clasp on the beads-of-rice bracelet is considered a drawback at its price point. One owner also noted the difficulty in sourcing replacement parts for older models. Overall, owners and reviewers rate the Aquastar Benthos 500 II highly for its blend of vintage charm, modern wearability, and unique monopusher chronograph functionality.

From video reviewers

The custom caliber movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.

Bohen StarDiver

Owners widely praise the BOHEN StarDiver for its superior finishing and attention to detail, with one owner comparing it favorably to luxury dive watches. Reviewers note its superb fit and finish for the price, highlighting a satisfying 60-click ceramic bezel and a comfortable 13.8mm case height. However, the watch's divisive, angular case and unique design elements, such as a left-side crown, triple-date window, and short hands, may not appeal to all tastes. On balance, owners and reviewers rate the BOHEN StarDiver highly for its exceptional finishing and unique design at its price point.
