AI Technical Summary
Technical Problem
In watches, the lubrication of the escapement mechanism is difficult to guarantee throughout its entire service life, especially the effective lubrication of the surfaces of components involved in timing, such as the balance wheel bearing, escape fork and escape fork tip, and escape wheel teeth.
Method used
The escape wheel's teeth are designed with at least one chamfered portion for each tooth. The chamfered portions have different geometric orientations to improve the distribution and retention of lubricant, including chamfered portions with different geometries to avoid continuous wear.
Benefits of technology
By improving lubrication performance, the long-term stability and lifespan of the escapement mechanism can be increased, and processing costs can be reduced.

Abstract
The invention relates to a timepiece escapement (100) comprising at least one escapement wheel (1) whose teeth (2) extend on both sides of a median plane (PM) and which comprises at least two teeth (2) provided with at least one bevel (20) connected to an impact surface (4) of the tooth, wherein the bevels (20) on two different teeth (2) have different spatial geometric orientations with respect to the corresponding impact surface (4) on the tooth provided with the bevel (20). The invention also relates to a timepiece, in particular a watch, comprising at least one escapement (100).
