A timing split function was added soon after, which allowed intervals between competitors to be recorded. Adapted from a pocket watch, the crown was mounted at the 12 o’clock position, and accuracy was improved to 1/100th of a second. This developed into the first wrist-worn chronograph, released in 1914. A top-mounted crown started, stopped and reset the smaller hands. The main, centrally-mounted hands of the instrument displayed the time, and an additional pair of smaller hands counted elapsed time. After Edouard’s death in 1892, the brand continued to develop timing products, the ‘Time of Trip’ dashboard mounted stopwatch receiving its patent in 1911. This interest in chronographs founded the company’s penchant for timing equipment. Not twenty years later, he had also patented the oscillating pinion: a compact component that allowed precise engagement of the chronograph function. Such was his enthusiasm for his work, that with just nine years under his belt making watches, he had already patented one of the first crown winding mechanisms. The brand originally started off as just Heuer, under the leadership of Edouard Heuer a watchmaker with a passion for innovation, he started making watches at the tender age of 20.
