The Marathon GSAR is a 41 mm automatic dive watch built to Marathon’s Search and Rescue specifications. Marathon’s current Standard-Issue listing identifies it as the Diver’s Automatic, Type II, reference WW194006SS-0130. The product details can be verified, but the specific watch worn for the Ride to Conquer Cancer—and any firsthand ride experience or formal event connection—has not been established.
What is the Marathon GSAR?
GSAR is commonly used for Government Search and Rescue. Marathon describes its Search and Rescue series as developed to Canadian Government requirements for professional SAR operations, and says the series was first introduced in the early 1990s. That is the manufacturer’s account of the line’s history and intended use, rather than an independent assessment of its performance.
The current Standard-Issue model is listed as the 41 mm Large Diver’s Automatic, Type II, reference WW194006SS-0130. Its specifications make it a substantial, tool-oriented automatic watch; they do not establish that this particular model was worn during a charity ride.
What are the current 41 mm GSAR specifications?
Marathon’s U.S. product page lists the following specifications for the Standard-Issue reference. They are manufacturer-provided details, not results from independent testing.

Is the GSAR a good dive watch?
The listed design includes features associated with a purpose-built dive watch: a unidirectional elapsed-time bezel, screw-down crown, sapphire crystal and a stated 30 ATM submersibility rating. Marathon also specifies tritium gas tubes alongside MaraGlo for illumination. Those characteristics make the GSAR a plausible choice for someone seeking a rugged, highly legible mechanical diver, but suitability depends on fit, comfort, maintenance and the wearer’s needs.

The dimensions deserve attention before buying. At 41 mm across, 14 mm thick and 48 mm lug-to-lug, it has a notably present case; the 20 mm lug width is useful when checking replacement straps. Try the watch on if possible, especially if you prefer low-profile watches or have a smaller wrist. Confirm strap width and hardware compatibility for any replacement strap rather than assuming every 20 mm option will fit.
What watch was worn for the Ride to Conquer Cancer?
The available product information does not identify the exact GSAR reference involved in the hands-on story, confirm that the author wore one on the Ride to Conquer Cancer, or establish a formal relationship between Marathon and the event. No event year, participant details or fundraising result can be substantiated here. The title’s ride context should therefore not be read as evidence of a documented test, partnership or charitable contribution.

Straps and practical fit
Marathon lists a three-piece rubber strap kit with the Standard-Issue watch, as well as optional 20 mm leather and nylon canvas straps and a Marathon x Bergeon spring bar tool. These are accessories named on the manufacturer’s page, not an independent assessment of their comfort or suitability for cycling. Check the exact strap’s dimensions, attachment hardware and intended use before purchasing; the 20 mm lug width alone does not guarantee fit.
