What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Yema Navygraf CMM.10

Owners widely report quality control concerns and suspect craftsmanship with the Yema Navygraf, with one user noting crooked text. A reviewer praised the Slim CMM.20 Limited Edition for its stylish, slim profile and classy finishing on a black lacquered enamel dial, though the audible micro-rotor spinning at its price point was a surprise. On balance, the consensus is that while the Yema Navygraf offers a stylish design, potential buyers should be aware of reported quality control issues.
