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.

Glycine Airman GMT

Owners widely appreciate the Glycine Airman GMT's classic pilot design and consider it a well-built watch, with some noting the 39mm models offer perfect sizing and 200m water resistance. Reviewers praise the plexiglass crystal and matte dial, while some owners find the GMT hand visually similar to the minute hand, making it difficult to read. Accuracy from the Sellita-based movement is described as acceptable, though dial lume pips are noted as weaker than the hands. On balance, owners and reviewers value the Glycine Airman GMT for its faithful reproduction of a classic pilot watch design, despite some legibility concerns with the GMT hand.
