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.

Fortis Flieger F-39 Werk 7

The Fortis Flieger is widely praised for its superb readability, robust build quality, and phenomenal fit and finish, with reviewers noting the practical Type-A dial and utilitarian design. The F-39 models are noted to wear large due to their lug-to-lug distance, and the UW-30 movement offers a 38-hour power reserve, while other variants feature a 70-hour power reserve. On balance, reviewers highlight the Fortis Flieger's modern, stylish take on pilot's watches, balancing legibility with unique aesthetics.
