A system and method that enables a person to understand the concept of “a timed schedule” and/or a “timed task”, so that they can more efficiently and/or effectively perform vocational and other life tasks and skills.

A timepiece including: a dial; a windshield glass having a plurality of curved surfaces that differ from each other in curvature; and a hand disposed between the dial and the windshield glass, wherein the windshield glass includes: a first curved surface having a first curvature and including a center of the windshield glass; a second curved surface disposed adjacent to the first curved surface and having a second curvature larger than the first curvature; and a third curved surface disposed adjacent to the second curved surface and having a third curvature larger than the second curvature, a thickness of the first curved surface and a thickness of the second curved surface are equal, and in plan view, a distal end of the hand is disposed on a center C side of the windshield glass with respect to a boundary between the second curved surface and the third curved surface.

A watch cover that covers the face of a watch. The watch cover has a plurality of receivers around the circumference of the watch cover. The plurality of receivers receive either a plastic or a glass capsule that snaps into the plurality of receivers. The plastic or the glass capsules have removable caps that allow the plastic or glass capsules to be filled with either a liquid or solid material prior to the plastic or the glass capsules being snapped into the plurality of receivers. The watch cover can have two wrist bands that attach to the watch cover. The wrist bands will have a plurality of wrist receivers throughout the length of the wrist bands. The wrist receivers will receive either the plastic or the glass capsules after they are filled with the liquid or the solid materials.

A timepiece dial includes a substrate having transmissivity and two or more types of transmissive color films provided at one surface of the substrate, in which the two or more types of transmissive color films do not overlap with each other in plan view as viewed from a direction perpendicular to the one surface of the substrate.

A system and method that enables a person to understand the concept of “a timed schedule” and/or a “timed task”, so that they can more efficiently and/or effectively perform vocational and other life tasks and skills.

At least one processor that identifies which of a plurality of exterior bodies individually formed in advance is an exterior body attached to a main body of an electronic device capable of executing at least a first function and a second function which are not display functions and are different from each other, enables at least the first function of the electronic device and disables at least the second function of the electronic device when the identified exterior body is a certain exterior body among the plurality of exterior bodies, and enables at least the second function of the electronic device and disables at least the first function of the electronic device when the identified exterior body is another exterior body different from the certain exterior body among the plurality of exterior bodies.

The invention relates to a watch case comprising: —a structure arranged to support a watch movement, and —a middle comprising an outer envelope connected to said structure and arranged to house said structure, said envelope comprising a network of articulated elements which form an outer wall of the outer envelope, the articulated elements being able to move with respect to one another so that said outer wall is deformable.

The present invention concerns a method for obtaining a finished or semi-finished zirconia-based article (1), the article having a metallic external appearance and non-zero surface electrical conductivity, characterized in that the method includes the steps consisting in: taking at least one zirconia article, pre-shaped in its finished or semi-finished form; placing said article inside a chamber (10) in which a gaseous mixture is arranged, this gaseous mixture including at least a first hydrogen and carbon based gas compound in a first concentration (C1) and a second hydrogen and nitrogen based gas compound in a second concentration (C2); heating the gaseous mixture until the molecules of the first and second compounds dissociate and keeping said article in the reactive atmosphere thereby created to obtain diffusion of the carbon and nitrogen atoms in the external surface (2) of said article and to form stoichiometric carbonitride (ZrC.sub.x—N.sub.y) at the surface, and prior to the step of heating the process gases contained in the chamber, a reduction step consisting in placing said article inside a chamber into which dihydrogen is injected and in heating the dihydrogen allowing diffusion towards the surface and release of the oxygen contained in said zirconia article.

The present invention relates to a covering element for a portable object made of a first material, the first material being a ceramic material having a first color, characterized in that the surface of said covering element is at least partially treated so as to exhibit at least one conversion having a different color from the first color.

A timepiece or jewelry component comprising a substrate and at least one decoration joined to the substrate, wherein it comprises a transparent coating covering at least one part of the substrate and at least one part of the decoration, the coating changing the perceptible color of the substrate without changing the perceptible color of the at least one decoration.
