WHY is the watch worn on the left hand?In 1904 Cartier's friend, the aviator
Alberto Santos-Dumont, asked Cartier to make a watch for flying. Cartier invented the Santos, the first wristwatch for men (mechanical). The Santos was an extremely wearable wristwatch.
During the First World War the wristwatch replaced the pocket watch and became popular among officers. The Santos wristwatch appeared as a tool to be worn on the left hand,
as most people were more handy with their right arm than with their left. When working, the main actions are performed with the right hand. To avoid damage, the watch was worn on the left hand.
Besides, a wristwatch had to be wound and the crown was on the right hand.
