![]() These stopwatches were able to accurately display timings of 1/50 and 1/100 second, a huge advancement on the 1/5 second displays of current stopwatches. And in 1916 Charles-Auguste Heuer, son of Edouard, created the Mikrograph and Semikrograph. The world’s first wrist-worn chronograph was released by the company in 1914. The Sphygmometer pocket chronograph, patented in 1908, revolutionised medical timing by allowing a doctor to determine a patient’s pulse rate after counting heartbeats for just 20 seconds. Heuer rose to this challenge, producing and patenting a range of chronographs that were fit for the job. He deemed this invention the “the perfected chronograph”, and it is still used by major watchmakers to this day.īy the beginning of the 20th century, the demand for more precise and accurate timings had reached a critical point, thanks to advancements across the fields of science and technology. In 1882 Edouard patented his first chronograph, and by 1887 he had perfected it with his patent for his improved ‘oscillating pinion’. This new innovation proved to be popular amongst buyers and makers alike and helped to change the course of watchmaking forever. Prior to his invention, a small key had been required to wind a pocket watch and keep it running. ![]() Technical innovation came naturally to Edouard, and he submitted his first patent in 1869 for a crown-operated, keyless winding system. Over the next few years, Heuer would move his company first to Brugg in 1864, and then onto Biel in 1867, where the business would remain for over 100 years. Based on the family farm in Saint-Imier, he became known for producing pocket watches under the Heuer name. In 1860, at the age of just 20 years old, Edouard Heuer opened his watchmaking shop.
