With a rich heritage dating back to 1939, one of Marathon’s main achievements is being a longstanding and trusted timepiece manufacturer for the Allied Forces. This relationship with the Allied Forces coincided with the height of the Second World War and began when the family-owned brand was just two years old. Now in its fourth generation, the family continues the proud tradition by offering a diverse range of military-grade instruments that measure time, temperature, and distance. The perfect fusion of Swiss engineering and careful craftsmanship, Marathon watches guarantee an outstanding level of quality and precision. Each piece is rigorously tested to ensure it passes quality control and meets the brand’s high durability standards. Committed to continuing its familial legacy, Marathon strives to deliver only the highest quality product experience.
