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 Combat Sub

The Glycine Combat Sub is widely praised for its exceptional thinness, with multiple sources highlighting its sub-11mm case height and comfortable wearability, even on smaller wrists. Owners appreciate its unique, non-homage aesthetic, refined finishing, and excellent value for money. Specific positive notes include a buttery smooth bezel action, tasteful indices, crisp font, and a matching date wheel. Accuracy is reported to rival COSC standards by one owner, and durability is noted as exceptional. However, some owners report inconsistent power reserve and sub-par lume that is difficult to read in low light. On balance, owners and community members rate the Glycine Combat Sub highly for its slim profile and unique design at an accessible price point.

From video reviewers

The slim case profile and comfortable wearability are praised. The bezel action received criticism for having slight play and a less-than-satisfying click.
