What people say

Owners + reviewers, side by side

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

Oris ProPilot X Calibre 400 Laser

The Oris ProPilot X Calibre 400 Laser is praised for its high-tech laser-etched titanium dial and the advanced Calibre 400 movement with a 120-hour power reserve. However, the dial's unique rainbow gradient is polarizing, with one owner finding it childish and preferring applied indices for better legibility and lume, while reviewers note the case shape may still require adjustment. The CHF 4,800 price is also flagged as steep for a time-only watch. On balance, owners and reviewers acknowledge the innovative dial and movement, but opinions are divided on its aesthetic appeal and value proposition.

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.
