What people say

Owners + reviewers, side by side

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

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.

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.
