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.

LONGINES SPIRIT CHRONOGRAPH

The Longines Spirit Chronograph is widely praised for its excellent value, featuring a COSC-certified automatic movement with a column wheel chronograph and impressive finishing for its price. Owners and reviewers highlight its solid build, elegant dial with spectacular lume, and comfortable bracelet with a secure clasp. The aviation-inspired design is noted for its legibility and personality, with some appreciating the historical five-star rating as a nod to Longines' heritage, while others find it unnecessary clutter. Accuracy is reported as impressive, with one owner noting +1.7 seconds over 24 hours, and the movement offers a 54-hour power reserve. On balance, owners and reviewers rate the Longines Spirit Chronograph highly for its blend of classic design, robust build, and strong value proposition.

From video reviewers

The Longines Spirit Chronograph features a high-quality ceramic bezel with satisfying bezel action. The watch's value as a mechanical chronograph under $3,000 is notable, particularly for its pilot watch design. However, the lume brightness is somewhat limited, and the finishing could be improved, with inconsistent execution of various finishes on the details.
