Timepiece indexing element

A timepiece indexing element, arranged to cooperate in a substantially coaxial manner, around an axis around which said indexing element extends, with a timepiece component including an indexing relief, including indexing parts arranged to cooperate with said indexing relief of said component for relative indexing between said indexing element and said component from a plurality of relative indexing positions, where said indexing parts are carried by a plurality of first elastic arms each including a first indexing surface, each said first elastic arm being arranged to exert a pushing force that is substantially radial relative to said axis on said component, and where said indexing element includes at least a first bearing surface which is arranged, in a free state in a service position, to remain at a distance from a second complementary bearing surface that said component includes, and in the event of impact, to cooperate in abutment and/or guide bearing with said second complementary bearing surface, wherein each said first bearing surface is carried by a second elastic bearing arm cantilevered inside said indexing element.
