Method for forming a transparent timepiece component including top and bottom surfaces: a transparent polymerizable material is chosen; there is applied to a plate a flexible female mold including a capillary network and having a contact surface which is the negative of the bottom surface, bordered by an edge; a cavity is delimited by the sealed juxtaposition of the edge with a plate having a contact surface which is the negative of the top surface; the material is injected through the capillary network to fill the cavity; the material is polymerized to obtain a rigid component; the component is removed from the plates by the deformation of this flexible mold. Hardness is improved by the UV exposition of this component.

A method of manufacturing an object including: impregnating a material comprising a plurality of boron nitride structures, the boron nitride structures comprising boron nitride nanotubes, or a hybrid of two or more forms of crystalline boron nitride structures, with a matrix material to form a composite material; moulding the composite material; and curing the composite material, wherein the object is at least partially fabricated from the composite material.

A decorative bezel unit includes a first bezel and a second bezel. The first bezel is made of a brittle material, and surrounds an opening of a timepiece case and is fixed to an upper side of the timepiece case. The second bezel is made of a brittle material, and is disposed on side of the timepiece case and fixed to the timepiece case so that sideward movement of the second bezel is restricted. Upward movement of the second bezel is restricted by the first bezel.

A watch including a gasket (18) arranged at the periphery of the glass (14), an intermediate portion (20) laterally surrounding the analogue display and defining a radial surface forming an axial stop for the glass, a solar cell (30) extending at least mostly between the lower level of the dial and the glass and being arranged behind the intermediate portion, which is formed at least partially by a translucent or transparent material and configured to make it possible for the incident light to propagate in the intermediate portion and to subsequently reach the solar cell. The gasket is also formed at least mostly by a translucent or transparent material and it forms with the intermediate portion axially a continuous medium. In variants, the gasket is arranged axially adjacent to the intermediate portion or it is axially separated from the intermediate portion by a translucent or transparent intermediate medium.

A horology or jewellery component, characterised in that it contains phase silicon nitride in a percentage by volume comprised between 99% and 100%.

A watch glass includes a first glass, a second glass and a decorative element. The second glass is connected to the first glass via a connecting intermediate layer. The decorative element is inserted in a setting, which is arranged in a watch glass recess. The watch glass recess is formed by a first recess in the first glass and a second recess in the second glass. Here, a space of the watch glass recess is defined by the first glass, the second glass and the setting. The space is filled with connecting material of the connecting intermediate layer, so that the setting is connected via the connecting material to the first class and the second glass.

A timepiece including: a case with an opening; and a first exterior located at the opening of the case. The first exterior includes a ring-shaped first member and a first protrusion protruding toward a center of the first member from a plurality of locations along a circumferential direction of the first member, and the first protrusion of the first exterior is located at an outermost location of the timepiece.
