Soon men dared to wear wrist watches without feeling self-conscious. By 1924, some 30% of man's watches were worn on the wrist. Today, the figure is 90%.
Then army officers discovered that the wrist watch was most practical for active combat. Race car drivers also loved to wear wrist watches, and pilots found them most useful while flying.
In the old days, queens included wrist watches among their crown jewelry. Later, they were worn by Swiss workers and farmers. Until World War One, Americans associated the watch with fortune hunters.
