A substrate for forming timepiece components includes a first part based on photostructurable glass and at least a second part based on at least one second material. One surface of the first part is made integral with a surface of the second part so as to form a one-piece timepiece component.

Timepiece component based on photostructurable glass

The invention relates to an external part including a first portion based on photostructurable glass, at least one second portion based on at least one second material. According to the invention, one surface of the first portion is made integral with a surface of the second portion so as to form a one-piece external part.

A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.

A temperature-compensated resonator including a body used in deformation, and a core of the body is formed by a material that is one of glass, ceramic glass, technical ceramic, and metallic glass. At least one part of the body includes a coating whose Young's modulus variation with temperature is of an opposite sign to that of the material used for the core, so that at least a first order frequency variation with temperature of the resonator is substantially zero.

A compensating balance spring for a thermally compensated sprung balance resonator including a core formed from at least one non-metallic material. The core is entirely coated with a layer which is moisture proof to render the balance spring less sensitive to climatic variations. The compensating balance spring can be applied to timepieces.

Resonator with reduced sensitivity to climatic variations

A compensating balance spring for a thermally compensated sprung balance resonator including a core formed from at least one non-metallic material. The core is partially coated with at least one layer which is moisture proof to render the balance spring less sensitive to climatic variations.

An element is arranged to cooperate with another part so as to form an encapsulation device for a component including the element at least partially coated with a metallization. The metallization includes at least one metal layer protected by an intermetallic compound which is coated by a non-diffused portion of a material whose melting point is lower than 250&#xb0; C. A method of fabricating the encapsulation device is also disclosed.

Method of manufacturing an encapsulation device

A method for manufacturing a component in a substrate including: a) modifying a structure of at least one region of the substrate to make the at least one region more selective; and b) chemically etching the at least one region to selectively manufacture the component.

An intermittent blocking mechanism for at least one escape wheel, that intermittent blocking mechanism cooperating with at least one regulating member or a balance which is actuated with an alternate motion under action of an elastic return mechanism, the intermittent blocking mechanism being pivoted in at least one bottom plate, and forming an inseparable single-piece component with the bottom plate. The intermittent blocking mechanism includes at least one pallet lever in a single-piece with the plate to which it is connected by the elastic return mechanism.
