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.

Oak & Oscar The Olmsted ExP-01

Owners widely praise Oak & Oscar The Olmsted ExP-01 for its exceptional finishing, comfortable bracelet, and smooth movement. The dial designs are a frequent point of admiration, with specific appreciation for the white, navy, and gray variants, as well as the orange seconds hand. The watch is considered fairly priced at around $1.5k and is noted for its versatility and "soul." On balance, owners rate Oak & Oscar The Olmsted ExP-01 highly for its overall quality, design, and the brand's customer service.
