In the 16th century, Peter Henlein made history with his portable clock called the “Nuremberg Egg” which was encased in an oval capsule and hung on a chain. It is considered to be the first watch ever made. Over a hundred years later, Christiaan Huygens developed a smaller, more accurate watch that was secured with a gold chain and made to fit in a pocket.
It wasn’t until the end of the 19th century that the wristwatch was invented, and at that time it was considered an ornamental item that only a lady would wear. But that changed with the advent of the first World War. Wristwatches were infinitely easier to use in the midst of battle, and as soldiers came home, they became de rigueur. Watch companies took advantage of this trend and developed increasingly better and more accurate timepieces.
