While the SSNAV-D Steel Navigator is intended to join Marathon’s other watches as part of the lineup they offer via government contracts (everything from military to LEOs, fieldworkers, and search and rescue outfits, with the NSN 6645-01-698-4275) the watch will also be available for sale via Marathon’s website and other points of retail starting at $800.
For that price, you get a single-pass nylon strap with a soft keeper or, for an additional $30, you can option their NATO-style DEFSTAN strap with steel hardware.
