Abstract (en)
[origin: WO2016199039A1] The invention relates to a resonator that is intended for equipping a timepiece control member and comprises a body (1) that is used when deformed. The body (1) is made of a glass material having a first thermoelastic coefficient (β1). Said glass material comprises a portion (3) that is locally modified such that said modified portion (3) has a second thermoelastic coefficient (02) that is different from the first thermoelastic coefficient (01), such that the resonator is temperature-compensated. The present invention also relates to a method for manufacturing said resonator. The invention also relates to a balance spring made of a material that is not necessarily glass but that is transparent at laser wavelengths.
