What people say

Owners + reviewers, side by side

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

Borealis Watch Co. Sintra

Borealis Watch Co. Sintra owners widely praise its well-executed design, featuring applied indices and a shimmering blue dial that some prefer over more expensive alternatives. The timepiece is noted for excellent build quality and high-end specifications for its price, including a Miyota 90S5 movement and a premium bracelet. One owner did not purchase due to its size not being 39mm or less, while the 90xx movements are considered reliable and accurate, though some find them noisy. On balance, owners rate the Borealis Watch Co. Sintra highly for its impressive design and build quality at its price point.

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.
