What people say

Owners + reviewers, side by side

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

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.

One reviewer notes the stock rubber strap requires modification for a proper fit. Overall, reviewers rate the Marathon MSAR (Medium Search & Rescue) Diver's Automatic highly for its focus on utility and ruggedness at its price point.
