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.

Sternglas Naos XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.
