A component of a winding device, in particular an automatic winding device, of a timepiece movement, wherein it is made of austenitic stainless steel and wherein it comprises at least one friction surface hardened by carbon or nitrogen type atoms introduced into the austenitic stainless steel over a predetermined depth.

A stop pawl for a horological movement, including a body provided on the periphery with a lug for latching with the toothing of a ratchet; a hub intended to cooperate freely in rotation with a fixed rod according to an angular displacement between an active position meshing the lug with the toothing of the ratchet and an inactive position, via intermediate positions; wherein the pawl includes at least one device for returning the pawl during its angular displacement, from the inactive position to the active position; and wherein the return device and the body are made in one piece. A horological movement and timepiece can include such a pawl.

The disclosure provides a can cover with a time indication function, and pertains to the technical field of food containers. The can cover comprises a cover body, and the can cover also comprises an indicating system for indicating the opening date of a can; the indicating system comprises a pointer and a plurality of scale lines; the scale lines are positioned on the surface of the cover body; the pointer is arranged on the surface of the cover body; one end of the pointer can rotate or swing in the range of the scale lines, and points to one of the scale lines. The can cover can indicate the opening date of the can, and assist a user to remember the opening date of the can, so that the opening date of the can can be known clearly, and bad and out-of-date canned food is avoided being eaten.
