What people say

Owners + reviewers, side by side

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

Marathon Arctic OSAR 46mm Automatic

Owners widely praise the Marathon Arctic OSAR 46mm Automatic for its overbuilt toughness and industrial, instrument-like aesthetic, with some preferring the Arctic dial for legibility. One owner notes the automatic movement may be unnecessary for rough use compared to a quartz option. Reviewers mention the MaraGlo luminous paint and a Sellita SW200-1 automatic movement. Some owners question its rising price and luxury positioning, with one reporting poor lume and movement performance. Overall, owners value the Marathon Arctic OSAR 46mm Automatic for its robust build and utilitarian design.

Glycine Airman No. 1 Purist

The Glycine Airman No. 1 Purist is praised as a faithful re-creation of a historical 24-hour watch, with one owner purchasing it for $620 and viewing it as a long-term keeper due to its heritage reissue status and vintage aesthetics. The 36mm size is noted as a conversation starter. However, the acrylic crystal is prone to scratching, with one example showing a small scratch over the date window. Some community members suggest pre-Invicta models may hold value better. Overall, owners appreciate the Glycine Airman No. 1 Purist for its authentic vintage appeal and unique dial, though the acrylic crystal requires careful handling.
