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 Jackson

Oak & Oscar The Jackson is a 40mm flyback chronograph praised for its balanced design and fine details, with reviewers highlighting the readability of the dial, particularly the new blue option and the 12-hour stacked subdial. The watch features a modular Eterna caliber movement, with one version utilizing the 3916M and another the 3907M, and is housed in a 40mm steel case. It is priced at $3,150 and includes two Horween leather straps and a watch wallet. On balance, reviewers find Oak & Oscar The Jackson to be a sporty, subtle chronograph with a comfortable wearability and an easy-to-read dial.
