Method of manufacturing a timepiece component

A machining device including at least one rotating spindle configured to hold a block to be machined and a laser that can be off-centered, the machine device being configured to employ a method of manufacturing a timepiece component, wherein the method includes;

• procuring the block to be machined;
• forming a timepiece component blank having a shape of revolution about an axis of revolution;
• machining the blank using an off-center laser beam having a direction which is not parallel to the revolution axis, does not cross the revolution axis, and is not tangential to the blank to be machined.

A timepiece component,

• wherein the timepiece component is made of a material having a hardness greater than or equal to 800 HV,
• wherein the timepiece component has a monobloc structure comprising a shaft and at least one tooth having a section which on a plane perpendicular to the shaft has a shape including a flared profile portion, a section normal to the shaft having a shape in which an orthoradial dimension increases in a direction radially away from the rotation axis.
