The invention is directed to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined direction. The saw chain includes: a plurality of cutting links, a plurality of driving links and a plurality of connecting links, the links being pivotally interconnected by rivets or the like to define the saw chain. The cutting links have respective cutting teeth disposed at a pregiven elevation above the guide bar. A plurality of non-cutting riders are mounted on selected ones of the links so as to be at an elevation corresponding approximately to the elevation of the cutting teeth for visibly marking the movement of the saw chain around the guide bar.
