摘要：
A method for treating a surface (2) of a base (1) of a timepiece component (10), in particular a balance spring, e.g. a balance spring made of a paramagnetic NbZr alloy, includes: a first step of depositing a first layer (41) of a first oxide or first nitride or first carbide; and a second step of depositing a second layer (51) of a second oxide or second nitride or second carbide.
