Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
The custom caliber movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.
Owners widely praise the Marloe Watch Company Morar 310 for its unique, steampunk-inspired aesthetic and excellent build quality, with many calling it a favorite watch. Reviewers and owners alike highlight its brilliant lume and playful dial design, while some note the versatility of strap options. The watch is considered good value at approximately £450/€530. Owners report accuracy as high as +1 second per day. Some find the all-polished look appealing, though one owner felt it was too shiny and another disliked the stock strap. The bezel clicks are described as less substantial than higher-end divers, with slight play when disengaged. One owner experienced static shocks while wearing the watch. Overall, owners and reviewers rate the Marloe Watch Company Morar 310 highly for its distinctive design and solid construction at its price point.
