Abstract: The invention concerns a timepiece member including a first axis and a first threading intended to cooperate with 5 a second threading provided on a second timepiece member. The first threading is configured so that a zone of contact between the first threading and the second threading extends over less than 50% of the height of the threads of the second threading or is configured so that the zone of contact between the first 10 threading and the second threading extends over less than 0.3 times the pitch of the threading.

Abstract: Method of manufacturing a watch component (10) for a timepiece, wherein it comprises a first stage of manufacturing a watch component (10) comprising a first surface (1), in which there is arranged at least one recess (20), that is to say a surface recessed from the first surface (1), and wherein it comprises a second finishing stage the watch component, leading to a change in the surface condition, more particularly the roughness, more particularly measured by the parameters Ra and/or Str, and/or the gloss, of the first surface (1) but not of the at least one recess (20) or of a portion exclusively of this at least one recess (20).

Abstract: Method for producing a surface of revolution of a clock or watch component comprising a step of machining, with a femtosecond laser beam, a first surface of the clock or watch component so as to obtain a second surface, in particular so as to obtain a second surface whose roughness Ra is less than 100 nm, or less than 70 nm, and then a tribofinishing step applied to the second surface so as to obtain the surface of revolution.
