What people say

Owners + reviewers, side by side

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

Fortis Novonaut N-42

Owners widely praise the Fortis B-42 Official Cosmonauts for its stunning fit and finish, excellent legibility, and a precise, grippy bezel, with one owner calling its bracelet the nicest they've ever owned. The Fortis Novonaut N-42 is described as a flawless beast with a WERK 17 column-wheel chronograph movement, featuring enhanced shock resistance and COSC adjustment, and is noted as a handsome tool watch with a beautiful dial and nice pusher action. However, the 42mm case of the B-42 wears larger than expected, and the Novonaut's 44mm case and chunky bracelet make it too large and heavy for many. The Fortis Titanium Legacy is a modern pilot's watch with a titanium case and bracelet, featuring a Kenissi WERK 13 movement with a 70-hour power reserve and three time zones. Overall, owners and reviewers highly regard the Fortis Titanium Legacy for its robust tool watch design and advanced movement technology, despite some concerns about case size and bracelet adjustability.

LONGINES SPIRIT FLYBACK

Owners widely praise the Longines Spirit Flyback for its attractive design, well-finished titanium case, and value as a chronometer-certified flyback chronograph. Specific positive notes include its fun and useful flyback function for cooking, and the perceived adventure-ready, indestructible feel of the titanium model. However, reviewers and owners consistently flag its 17mm thickness as a significant detractor from wearability, with some finding it too chunky for daily wear. There is also a split opinion on the dial design, with some preferring the older five-star motif and gold hands/markers, while others appreciate the cleaner, simplified dial and cutoff numerals. The Longines Spirit Flyback is priced around $5,350-$6,500 USD. Overall, owners and reviewers rate the Longines Spirit Flyback highly for its flyback chronograph complication and attractive design, despite widespread concerns about its thickness.

From video reviewers

The Spirit Flyback's heritage-inspired design is a notable strength, with a distinctive look reminiscent of the original Flyback Chronograph. The watch's price point is somewhat high compared to its competitors, which might be a drawback for some buyers. Reviewers disagree on the watch's design, with one reviewer feeling it needed more of an edge to stand out in the Spirit collection, while another praises its heritage-inspired style.
