The Marathon Steel Navigator SSNAV-D Quartz (ref. 41mm-steel-navigator-w-date-ssnav-d-on-black-3-piece-rubber-strap-kit) is a quartz pilot watch, with a 41mm 316l stainless steel case, 11mm thick, powered by the Swiss High-Torque Quartz movement. Water resistance is rated to 60m, under a sapphire crystal. Manufacturer MSRP is $1,300.
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.
