Abstract
Official abstract text for this publication.
A method for adjusting a rate of a timepiece after encasing a movement to ensure a better rate for the timepiece.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for adjusting a rate of a timepiece comprising: placing a movement including a balance/balance spring resonator inside a timepiece case without a back cover or without a whole of the back cover; measuring a rate of the timepiece; determining a correction value to be applied to a balance inertia to obtain a desired rate; altering the balance inertia according to the correction value by adding material to the balance by fitting the movement into the case without the back cover or without the whole of the back cover. 2. A method according to claim 1 , wherein the measuring a rate is performed with no contact with the balance/balance spring resonator. 3. A method according to claim 1 , wherein the measuring a rate is performed optically or acoustically. 4. A method according to claim 1 , wherein the correction value corresponds to a symmetrical arrangement of at least two masses of material on the balance to alter balance inertia without altering a center of mass of the balance. 5. A method according to claim 2 , wherein the correction value corresponds to an asymmetrical arrangement of at least one mass of material on the balance to alter inertia of the balance and its center of mass. 6. A method according to claim 1 , wherein the adding material is performed by a phase of jetting material onto the balance. 7. A method according to claim 1 , wherein the material comprises an adhesive, a paint, or a metal suspension. 8. A method according to claim 1 , wherein a material jetting is followed by a solidification of the jetted material.
