The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its high legibility, featuring large hour markers and a white dial with applied indices. A functional date magnifier is present. The watch utilizes a reliable Sellita SW200-1 automatic movement. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. On balance, reviewers highlight the Marathon OSAR-D (Original SAR with Date) Automatic 41mm's strong legibility and functional design as its primary strengths.

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.
