[origin: JP2017151080A] PROBLEM TO BE SOLVED: To provide a method of attaching a balance spring so that it does not deviate from its static position without inducing a mechanical stress in the balance spring.SOLUTION: A method of attaching a final outer coil (12) of a balance spring (4) for timepiece to an inside of a groove (70) disposed in a stud (14) is provided. This method includes a step of adhesively bonding the final outer coil (12) of the balance spring (4) for timepiece using a fluent adhesive having a viscosity of 200-400 mPa s.SELECTED DRAWING: Figure 2B
