Marathon Watches is a Canadian watch company with roots dating back to 1939, though the Wein family’s involvement in watchmaking stretches back to the early 1900s. Founded in Montreal by Morris Wein, Marathon built its reputation producing timing instruments and military watches for Allied forces during World War II. Today, the brand remains one of the few companies still manufacturing watches to official military specifications for government and military use.

What makes Marathon unique is its focus on true utility. Marathon watches are designed in Canada and manufactured in Switzerland, combining Swiss production quality with genuine military heritage. Models like the GSAR and TSAR are known for their rugged construction, tritium tube illumination, and highly legible dials built for search and rescue operations, diving, and field use.

Unlike many modern tool watch brands, Marathon continues to prioritize function over luxury marketing. That authenticity has earned the brand a loyal following among collectors, military personnel, and enthusiasts who appreciate purpose built watches with real operational history.
