The watch includes a GMT bezel for dual timekeeping and a synthetic sapphire crystal. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Auto highly for its robust tool-watch design and reliable tritium illumination.

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.
