Abstract

Disclosed is a method for identifying a timepiece including a first component, e.g. the movement, and a second component, e.g. the case. A first zone of the first component of the timepiece is photographed with sufficient enlargement to show therein the tracks and flaws in or on the substrate of the first component in this first zone resulting from the process of manufacturing the timepiece and in particular the tracks or flaws produced when the second component is fitted into the first component. An identification mark (label, chemical or physical modification of the substrate) is applied to a second zone of the second component of the timepiece. These tracks or flaws are converted into a unique code by an appropriate algorithm and this code is associated with at least one item of information contained in the identification mark to form a unique and complete identifier of the item.

Claims

1. Method for identifying a timepiece comprising a first component and a second component, said method comprising the following steps:

photographing a first zone chosen on the first component of the timepiece with sufficient enlargement to show the tracks or flaws in or on the substrate of the timepiece in this first zone resulting from the process of manufacturing the timepiece, said tracks or flaws in or on the first zone comprising scratches produced when the second component is fitted into the first component;

using an appropriate algorithm to convert the tracks or flaws of the first zone which are picked out by photography into a unique code to form a unique identifier of the timepiece;

storing the unique identifier of the timepiece in a database to permit authentication of the timepiece in the future by comparison with a new unique code obtained after conversion by the algorithm of the tracks or flaws picked out by a new photograph of said first zone;

applying an identification mark to a second zone chosen on the second component of the timepiece, said mark containing at least one item of information characterising the timepiece;

associating said at least one item of information contained in the identification mark with the unique identifier of the timepiece and storing it with said unique identifier in the database to permit authentication of the timepiece in the future by comparison of the identification mark and/or a new unique code obtained after conversion by the algorithm of the tracks or flaws picked out by a new photograph of said first zone.

2. Method for identifying a timepiece as claimed in claim 1, wherein the unique identifier further comprises information characteristic of the first zone permitting its location on the timepiece.

3. Method for identifying a timepiece as claimed in claim 1, wherein the first zone is chosen on a visible part of the outside of the timepiece.

4. Method as claimed in claim 1, wherein the identification mark is obtained by chemical or physical modification of the substrate of the second component of the timepiece in the second zone.

5. Method as claimed in claim 1, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.

6. Method as claimed in claim 1, wherein the first component is formed by the movement of the timepiece and the second component is formed by the case of the timepiece which is intended to receive said movement.

7. Method as claimed in claim 6, wherein the first zone is the pivot of the seconds hand or the centre post of the movement of the timepiece.

8. Method for identifying a timepiece as claimed in claim 2, wherein the first zone is chosen on a visible part of the outside of the timepiece.

9. Method as claimed in claim 2, wherein the identification mark is obtained by chemical or physical modification of the substrate of the second component of the timepiece in the second zone.

10. Method as claimed in claim 3, wherein the identification mark is obtained by chemical or physical modification of the substrate of the second component of the timepiece in the second zone.

11. Method as claimed in claim 2, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.

12. Method as claimed in claim 3, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.

13. Method as claimed in claim 4, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.

14. Method as claimed in claim 2, wherein the first component is formed by the movement of the timepiece and the second component is formed by the case of the timepiece which is intended to receive said movement.

15. Method as claimed in claim 3, wherein the first component is formed by the movement of the timepiece and the second component is formed by the case of the timepiece which is intended to receive said movement.

16. Method as claimed in claim 4, wherein the first component is formed by the movement of the timepiece and the second component is formed by the case of the timepiece which is intended to receive said movement.

17. Method as claimed in claim 5, wherein the first component is formed by the movement of the timepiece and the second component is formed by the case of the timepiece which is intended to receive said movement.

18. Method as claimed in claim 8, wherein the identification mark is obtained by chemical or physical modification of the substrate of the second component of the timepiece in the second zone.

19. Method as claimed in claim 8, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.

20. Method as claimed in claim 9, wherein the identification mark is not visible from the outside of the timepiece without disassembling the timepiece.
