The guide bearing includes a blade (3) and a surface (5) for coming into contact with and holding the end of the rotary shaft of the sprung balance. The contacting parts are made of a material with a Young's modulus of less than or equal to 100 GPa and/or to reduce the coefficient of friction of the contacting parts. The device also includes a solid body (15) with a guide opening, such as a hole jewel (15), disposed along the axis of the rotary shaft (6) in a centred position. An end of the shaft passes through the opening without too much angular play caused by the effect of gravity.Type: ApplicationFiled: February 16, 2023Publication date: September 14, 2023Applicant: ETA SA Manufacture Horlogere SuisseInventors: Thierry CONUS, Raphaël Courvoisier, Jean-Luc Helfer, Sylvain Huot-Marchand
