A thermal protection case for timepiece, including, in a casing, a device for holding a case of a timepiece, including first elastic pistons with mobile supports each including at least one component thermally less conductive than the casing and the case and creating a thermal barrier between them, and opposite second supports each including a pillar each with at least one component thermally less conductive than the casing and the case and creating a thermal barrier between them constituting a fixed banking support, or by a second elastic piston including a second mobile support arranged to come to bear on the case and including at least one component thermally less conductive than the casing and than the case and creating a thermal barrier between the casing and the second mobile support.

Disclosed is a device case including: a case main body; a second exterior member attached so as to surround an entire periphery of an upper outer periphery of the case main body; and a first exterior member attached so as to surround at least an upper outer periphery of the second exterior member and the case main body. The second exterior member is formed of a material softer than the first exterior member and interposed between the case main body and the first exterior member along the upper outer periphery of the case main body, and has at least a part of an outer peripheral side surface covered by the first exterior member.

A horological resonator mechanism (100) including a structure (1) and an anchor unit (30) from which is suspended at least one inertial element (2) arranged to oscillate, with a first degree of rotational freedom RZ, about a pivot axis (D) extending in a first direction Z. The inertial element (2) is subjected to return forces exerted by a flexible guide (200) forming a virtual pivot, the anchor unit (30) being suspended from said structure (1) by a flexible suspension (300) arranged to allow said anchor unit (30) to move with a plurality of degrees of freedom. A retaining device (10) provides the flexible suspension (300), which is configured to damp the rotation of the inertial element (2) and of the flexible suspension (300) about the second direction X, and/or about the third direction Y.

Aspects of the subject technology relate to electronic devices with electronic components housed within cavities of the electronic device. Liquid occlusion may be mitigated by ejecting the occluding liquid with thermally controlled pressure modulation. An electronic device includes a housing having an opening and also includes electronic components disposed within a first cavity adjacent to the opening and exposed to an environment external to the housing via the opening. The device includes a heating element disposed within a second cavity adjacent to the first cavity. The device includes processing circuitry configured to determine that the opening is occluded and activate the heating element to eject a liquid through the opening to the environment by increasing a gas pressure within the second cavity based on a change in temperature in the second cavity by heating a gas volume inside the second cavity with the heating element.
