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

The Marathon OSAR-D (Original SAR with Date) Automatic 41mm is noted for its highly legible white dial with applied hour markers and a functional date magnifier, emphasizing its tool-watch purpose. Its Swiss-made Sellita SW200-1 movement is considered reliable and serviceable. One reviewer found the bracelet lacked refinement and preferred the rubber strap option. Overall, owners and reviewers appreciate the Marathon OSAR-D (Original SAR with Date) Automatic 41mm for its excellent legibility and robust movement.

Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46

Owners widely praise the Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46 for its anti-reflective sapphire crystal, legible dial, and strong C3 lume.

Some owners appreciate the clean, unbranded dial, aligning with traditional Flieger design. However, one owner notes the watch runs fast, requiring frequent time adjustments, and another commenter feels the date complication detracts from the Flieger aesthetic.
