What people say

Owners + reviewers, side by side

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

Spinnaker Fleuss 40 Automatic

Owners find the Spinnaker Fleuss 40 Automatic a good size for smaller wrists, though one owner notes the lume is too diffuse for easy nighttime reading. The pilot-style crown is an unusual feature for a dive watch. Overall, owners value the Spinnaker Fleuss 40 Automatic for its wearability on smaller wrists.

From video reviewers

The coral red dial is a unique aesthetic. The watch is a strong contender for best-in-class under $300.

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.
