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.

Ventus Watches Northstar

Owners praise the Ventus Northstar for its overbuilt and practical diver watch aspects, with perceived quality far above its price point. One owner notes the brass case measures 40mm with a 45mm lug to lug and 13mm thickness, featuring a double-domed sapphire crystal with inner AR coating. The case is rated for 300m water resistance. Some owners find the N1 version's dial underwhelming and the rubber strap flimsy, while one owner reports the white dial WD007ST has a noticeably misaligned date wheel. Overall, owners rate the Ventus Northstar highly for its exceptional value and robust build quality at its price point.
