As we all know, Switzerland holds a leading position in the manufacture of self-winding watches.
In 1893, A self winding watch with reserve power indicator was designed and put into mass production by a swiss watch factory.
Here below is a typical movement used in one of the many self-winding watches made in Switzerland today.
So do not think that automatic and power reserve indicators and many other design was design yesterday or recently. They have been around for ages. Hope you learn something today.
