    Abstract: A method of increasing concentricity in use of a spiral hairspring mechanical timepiece; the hairspring having an inner terminal end portion for engagement with a collet, an outer terminal end portion for engagement with a stud, a first limb portion extending from the inner terminal end portion towards the outer terminal end portion, and a stiffening portion positioned at the outer turn of the hairspring and having a cross-sectional second moment of area different to that of the first limb portion such that bending stiffness of the stiffening portion has a greater bending stiffness than the single limb portion. The method includes modifying cross-sectional second moments of an area of the first limb portion and the stiffening portion by minimizing a cost function throughout the amplitude of the rotation of hairspring in use, the cost function being correlated to the net concentricity of the hairspring.

    Abstract: A process operable uses a computerized system for displaying an article from a set of wearable articles or accessories. The article is displayed based upon a correlation between data indicative of features of mental impression of an article and the displayed article, and the computerized system includes a touch sensitive input device, a process module and a visual display module operably interconnected together via a communication link. The process includes the steps of (1) entering via a touch sensitive input device a first visual representation indicative of at least a portion of a mental impression of an article, wherein the first visual representation is a two-dimensional representation in a first predetermined viewing plane; (ii) in a processor module, comparing during step (i) data derived from input of the first visual representation and other data sets; and (iii) displaying on a visual display module a visual representation of at least a first article corresponding to the other data sets.

    Abstract: A method of forming a non-optically detectable identifiable marking invisible to the naked eye is formed from plural recesses of multiple levels at an outer surface of an article formed from a solid-state material. The method includes forming plural recesses of multiple levels within a predetermined region of a photoresist applied to an outer surface of an article formed from a solid-state material. The plural recesses are formed by grayscale lithography and the recesses extend at least partially through the photoresist and towards the outer surface of the article formed from a solid-state material. The method also includes applying an etching process such that at least a portion of the outer surface of said article is exposed and etched to form plural etched portions extending into the article from its outer surface and corresponding to plural recesses; wherein said predetermined region of said photoresist defines an identifiable marking to be applied to the outer surface of said article; wherein said plurality of etched portions forms the non-optically identifiable marking on the outer surface of said article.
