A watch includes a watch body, a watch face attached to the watch body and having an opening, and a pointer. The pointer includes an extension portion disposed to sandwich the watch face between the extension portion and the watch body and extending from the opening to face an upper surface of the watch face, and a support portion protruding from the watch body into the upper surface of the watch face via the opening, and connected directly to the extension portion. The pointer includes a change portion formed in the extension portion to change a posture of the extension portion such that a front end of the extension portion is raised with respect to a base end of the extension portion to be apart from the watch face. The watch face is removed from the watch body along the extension portion raised by the change portion.

A method for marking a product (1) with a photoluminescent mark, said mark comprising a photoluminescent portion (10) which is transparent under normal light conditions and revealed by photoluminescence under UV illumination, said mark further comprising a non photoluminescent portion (9) which is transparent under normal light conditions as well s under UV illumination, said method comprising: deposing on said product a stack, said stack comprising alternatively layers (2,4) such as AIN, with a thickness of less than 1 micron and layers (3) of a second material, such as GaN with a thickness of less than 10 nm; raising the transparency of said non photoluminescent portion (10) with a deposition of transparent material (6) or incorporation of ions into said non photoluminescent portions.

The present invention is directed to devices that may be used to help young children stay in bed or their room until it is time to get up. The device may be configured as a clock. The clock may be programmable to have a duration of a nap time, or a time when the child is able to get up. A visual countdown timer may be provided with the device (e.g., on the clock face), which may include a graphical representation of the remaining fraction of time before get up time. The visual countdown timer may not include number indicia, but rather includes a graphic (e.g., ring extending about the perimeter of the clock face), which gradually diminishes as the predetermined get up time is approached. A reward drawer may also be provided, which automatically unlocks at the get up time, and provides the child with a prize.

According to an aspect, there is provided a light apparatus, the light apparatus comprising an outer housing comprising a translucent portion; a main light source positioned inside the outer housing for generating light, wherein light generated by the main light source is incident on the translucent portion; and a display light source positioned inside the outer housing for projecting information onto a part of the translucent portion on which light is incident from the main light source.

A water-resistant watch case of a diving watch, includes at least one back mounted on a lower side of a middle part, and a crystal mounted on an upper side of the middle part. The crystal includes an annular peripheral surface to be fastened with an amorphous metal gasket on an inner annular surface that is complementary in shape, on the upper side of the middle part. The annular peripheral surface of the crystal is inclined towards the inside of the watch case at a determined angle less than 90 relative to a central axis perpendicular to a plane of the watch case to distribute stresses between the crystal and the middle part due to the water pressure during a dive. The annular peripheral surface and the inner annular surface are conical in shape.

A water-resistant watch case of a diving watch, includes a back mounted on a lower side of a middle part, and a crystal mounted on an upper side of the middle part. The crystal includes an annular peripheral surface mounted by a first portion of an annular gasket made of amorphous metal on an inner annular surface that is complementary in shape, on the upper side of the middle part. A second portion of the gasket on the first portion of the gasket maintains the crystal against the middle part. The annular peripheral surface of the crystal is inclined towards the inside of the watch case at an angle less than 90 relative to a central axis perpendicular to the plane of the watch case to distribute stresses between the crystal and the middle part due to the water pressure.

The invention relates to a method for fabrication of a one-piece, metal-based component of simple shape offering the illusion of faceting and/or chamfering for forming all or part of the exterior part of a timepiece.

A method that is for manufacturing a timepiece provided with a personalized decoration, visible in particular when the timepiece is worn, includes constructing the timepiece and producing the personalized decoration on all or part of a body of the timepiece. Producing the personalized decoration includes selecting from a human-machine interface of an electronic device a single portion of a reference digital graphical representation, in particular of an ephemeral reference digital graphic representation, and applying a coating of decorative material on all or part of the body of the timepiece as a function of the descriptive characteristics of the selected single portion.

A system for transforming a regular smartwatch into a luxury item, comprising, a smartwatch unit including at least the display unit of the smartwatch; and a box including a housing to accommodate said smartwatch, said box having a cover being openable and closeable to cover said display unit, wherein said cover has at least one hole so that a corresponding portion of said display unit is visible to a user when said cover is in closed position, wherein when said cover is in closed position, the smartwatch unit displays the output of the smartwatch in on said corresponding portion of the display.

The invention relates to a dial for a timepiece including a support and a mother-of-pearl sheet, the mother-of-pearl sheet having a front face and a rear face facing said support and on which a pattern has been printed. The mother-of-pearl sheet has a thickness between 50 m and 100 m so that the pattern printed on the rear face of the mother-of-pearl sheet appears transparently through the mother-of-pearl under normal conditions of illumination.
