The present invention relates to a piece, in particular for jewellery or timepieces, made of a material comprising a synthetic matrix (2) loaded with particles (3) of a precious or semi-precious stone, said particles (3) having a particle size d90 comprised between 50 m and 2 mm, preferably between 100 m and 1 mm, and, more preferably between 150 m and 500 m.

An electronic device may include a main body including a front plate, a rear plate disposed to be spaced apart from the front plate, a lateral member surrounding a space between the front plate and the rear plate, and a display viewed through at least a portion of the front plate. The electronic device may further include a housing having a space therein and combined with a strap at one side thereof in a first axial direction, a first fastening part protruding from another side of the housing toward the main body and detachably connected to the main body, a second fastening part formed in the main body and engaged with the first fastening part, and a button disposed in the housing, exposed at least in part to an outside of the housing, and moving the first fastening part to be separated from the second fastening part.

The invention relates to a protective device that fits over a wristwatch or another instrument having a face comprising (i) a band for encircling the wrist of a user with an opening through which the face of the wristwatch or other instrument is visible, and (ii) a protective cover, wherein the direction of fastening the protective device around the wrist of the user and the direction of fastening the protective cover to the band of the device is in opposite directions, thereby ensuring that the opening in the protective device is centred over the face of the wristwatch or other instrument. The invention further relates to a method of protecting a wristwatch or another instrument having a face with the use of the protective device of the invention.

A composition for impregnating a watchstrap or parts thereof is disclosed, the composition comprising a) an organic solvent or a sol-gel, b) at least one active organic compound comprising, preferably consisting of, a phosphonate group PO.sub.3H and an hydrophobic or hyper-hydrophobic group, and c) optionally one or more functional groups selected from i. an antifouling functional group and ii. a bioactive functional group,

Further, two processes for functionalizing a watchstrap or parts thereof are disclosed, one comprising impregnating a watchstrap or parts thereof with the composition containing the organic solvent, the second comprising impregnating a watchstrap or parts thereof with a silica sol-gel solution, which optionally comprises at least one active organic molecule as defined above.

A piece of jewellery made of a natural elastomer composite material, wherein the natural elastomer composite material includes a natural elastomer matrix wherein between 0% and 6% cellulose fibres, between 0 and 5% anti-odour agents, and between 0 and 30% silica are dispersed.

A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

An illuminated accessory. The illuminated accessory includes a housing that may be elastic, a power source inside the housing, electric lights connected to the power source, and a power switch to control the electric lights and/or other components of the illuminated accessory, such as a camera, a microphone, a clock, and/or a timer. The illuminated accessory may be configured to wrap around a wrist of an individual and worn as a bracelet, and/or may be configured to wrap around a device, such as a hair trimmer, and used as a light source when performing an activity, such as trimming hair.

A watchband can comfortably secure an electronic device to a wrist of a user. The watchband can include a base having a contact surface opposite an engagement surface, contact loops on the contact surface for contacting a user, and engagement loops on the engagement surface for engaging hooks. The hooks can be provided on the engagement surface, opposite some of the contact loops. The base can include base threads, and the contact loops and engagement loops can be formed by contact threads and engagement threads woven about some of the base threads between the contact surface and the engagement surface. Between adjacent engagement loops, the engagement thread can be more securely attached to the base than is the contact thread between adjacent contact loops.

A device capable of being used for a long time is achieved. A power supply, a connection method of a power supply, or a connecting member, for easy attachment and detachment and non-detachment when in use, is provided. A power supply, a connection method of a power supply , or a connecting member for easy replacement is provided. A highly designed power supply is provided. Power from a battery is supplied to an electronic device through a connecting member including a pipe, a spring, and a pair of pivots. The pair of pivots are electrically insulated from each other, and electrically connected to any one of a pair of electrodes of the battery. The electronic device into which the pair of pivots are inserted includes a pair of bearings capable of receiving power.

A foldable cup bracelet is provided. The foldable cup bracelet includes a sheet of resilient material, a first pair of fasteners, and a second pair of fasteners. The sheet of resilient material is foldable between a bracelet configuration and a cup configuration. The bracelet configuration includes a continuous band having an inner surface and an outer surface. The cup configuration includes a first side wall and a second side, and defines an interior for receiving a liquid or other substance between the first and second side walls. The cup configuration may form a drinking cup. The first pair of fasteners is configured to retain the sheet of resilient material in the bracelet configuration, and the second pair of fasteners is configured to cooperate with the first pair of fasteners to retain the sheet of resilient material in the cup configuration.
