Pilot watch has a very important role in wristwatch’s history. The earliest wristwatch was just a pocket watch attached to a leather strap wearing around the wrist, and it was not popular. Until the early 19th century, Alberto Santos-Dumont, an aviation pioneer, made complain to his friend, Louis Cartier, about the inconvenience of using pocket watch during his flight, Cartier, thereafter, developed the first pilot watch. It is also known as the first mass-produced wristwatch. Later during the First Boer War, development and production of watches have a substantial growth due to the great need of coordinating troop movements and synchronizing attacks. Since 1917, the British War Department began giving soldiers wristwatches. At that time, one soldier in every four wore a watch, and the other three have to get one soon as they could. Until the end of the war, almost every soldier was given a watch. After war, wearing a watch has become a fashion. In another word, military and pilot watches have accelerated the development of watches by decades. In appreciation of the pilot watch’s contribution to the development of wristwatch, DELTAt’s produced the SoRa.
