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 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.
