Founded in 1850 as a small workshop in the Swiss Jura Mountains, TAG Heuer today is a leader in the luxury watch market. Since its inception, TAG Heuer has demonstrated a passion for accurately measuring even the smallest increment of time. It is the only watchmaker to develop a mechanical automatic chronograph movement that displays 1/10th, 1/100th and 1/1000th of a second, as well as the only brand to capture 1/10,000th of a second. The brand's legacy is peppered with displays of engineering prowess, including the world's first oscillating pinion, patented in 1887, and the Monaco V4, which features a double-patented belt-driven movement that shatters the basic tenets of how a watch keeps time. Through a constant pursuit of excellence and innovation, TAG Heuer creates timepieces that are a defining symbol of state-of-the-art originality.
