Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Fortis Flieger is widely praised for its robust build quality, superb readability, and excellent fit and finish, with reviewers highlighting the utilitarian dial and Brixtrack markers. Some find the 39mm case wears large due to its 50mm lug-to-lug span, while others note the 41mm versions offer better proportions. The Werk 7 movement provides a 70-hour power reserve, though one review mentions the UW-30 movement in a 39mm model has a 38-hour power reserve. On balance, reviewers rate the Fortis Flieger highly for its practical design and solid construction at its price point.
The Marathon Steel Navigator SSNAV-D Quartz is widely praised for its high-accuracy Swiss Made ETA F06.412 HeavyDrive-PreciDrive quartz movement, rated at +/- 10 seconds per year, and its tritium lume. Reviewers and owners highlight its functional tool-watch appeal, noting the sandblasted steel case with an asymmetric design, excellent bi-directional bezel action, and drilled lug holes. Some owners find it perfectly suited for sport/rugged use, though not necessarily as an everyday watch. One owner points out that the case's distinctive asymmetry deviates from current aesthetic trends. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV-D Quartz highly for its robust build and exceptional timekeeping accuracy at its price point.
