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.

CWC Automatic Divers Watch Mk.2 Black

Owners widely praise the CWC Automatic Divers Watch Mk.2 Black for its excellent case finishing, clear sapphire crystal, and significantly improved lume compared to earlier models. The 120-click bezel action is consistently highlighted as perfect, and the 41mm case size is noted as wearing close to perfectly, with one reviewer specifically mentioning its modest 12mm thickness. Some owners prefer a matte finish for a more tool-like appearance, though polished versions offer a dressier look and easier scratch removal. Overall, owners rate the CWC Automatic Divers Watch Mk.2 Black highly for its build quality and legibility at the price.

From video reviewers

The bezel action is smooth. The price has increased due to popularity.
