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.

Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322

Owners widely praise the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 for its gorgeous, color-popping black mother-of-pearl dial and good case finishing, with some appreciating its distinct bead-blasted case and H-link bracelet. The $375 price is noted as a strong value for a true mother-of-pearl watch. However, opinions are divided on the dial text font and the Islander logo, with some finding them unattractive and others seeing them as minor issues on an otherwise appealing tool watch. On balance, owners rate the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 highly for its striking mother-of-pearl dial and value proposition.
