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 Worldtimer

The Glycine Airman Worldtimer is widely appreciated for its classic pilot watch design and comfortable wearability, with owners specifically praising the 40mm GL1048's size and the 39mm Airman 18's legibility and build quality. The Airman 18's dial lume pips are noted as weaker than its hands, and some owners find the GMT hand on certain models difficult to read due to its thinness and lack of lume. Accuracy is generally acceptable, with one owner reporting no flaws and another noting a Sellita-based movement kept acceptable time. On balance, owners and reviewers rate the Glycine Airman Worldtimer highly for its faithful reproduction of a classic design and excellent value.
