Marathon OSAR-D (Original SAR with Date) Automatic 41mm

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.

Thorn Diver Watch

Owners widely praise the Thorn 40mm NH35A Diver Automatic Watch for its impressive case finishing, featuring sharp polished chamfers and nice brushing, along with great lume and excellent wrist presence due to its 40mm case and ideal lug-to-lug measurement. The vintage aesthetic with yellowish hands and old-fashioned dial details is also a highlight, as is the explorer dial. The watch is considered well-made and offered at a great price, with the NH35 movement and 120-click bezel being impressive features. However, some owners note that the dial text on certain models does not match the logo style, and one owner reported the water resistance as 30M splash proof, not 300M. Some owners also report the watch as incredibly fragile. On balance, owners rate the Thorn 40mm NH35A Diver Automatic Watch highly for its finishing, vintage aesthetic, and value at the price point.
