Composite timepiece and method for producing same

A method for manufacturing a timepiece, comprising:

• micro-manufacturing or micro-forming at least a first part from at least a first material;
• nebulizing an ink in the form of a solution or suspension of micrometric, submicronic or nanometric particles of at least a second material;
• depositing, on said first part, without molding, at least a second part of said piece made from at least the second material, wherein said depositing includes spraying the nebulized ink on the first part of the piece to form said second part;
• and
• treating the second material to connect the second part to the first part by hardening said second part,
• wherein the first part is a balance;
• and
• wherein the second material of the second part forms an inertial mass deposited on the balance to correct the inertia of the balance and wherein the second material of the second part is further configured to poise the balance having a predefined mass;
• wherein the second part includes flanks forming an angle between 10° and 89° with the surface on which it is deposited;
• wherein the second part is deposited at the periphery of the balance and extends substantially to the balance plane.
