No insignia, no unit crest, just the Marathon name over a matte black dial: the Standard-Issue TSAR WW194007SS-0110 is the purist's version of the 41mm Tritium Search and Rescue diver. It is a Swiss quartz dive watch that looks like what it is, a piece of equipment, on a stainless steel bracelet.

Standard-Issue, sometimes written NGM for "no government markings," means the dial carries none of the official text you'll find on some Marathon issue variants. What remains is pure function. Large tritium-lit indices and high-torque hands give you an instant read, a date sits at 4:30 where it stays out of the way of the hands, and the 60-minute bezel times anything from a dive to a parking meter. The matte finish keeps glare off the dial, which matters more in daily use than most spec sheets let on.

This is the configuration for someone who likes the history of military-supplied watches but would rather not wear a badge they didn't earn. Marathon has supplied militaries since its first RCAF order in 1941; the Standard-Issue dial lets you enjoy that pedigree quietly.
