Method for manufacturing an electroformed timepiece component: the same first alloy including a first precious metal is selected to make both functional inserts and an electroformed shell; these inserts are made; an electroforming substrate having a complementary profile to the inner profile of this component is formed in a second sacrificial material; these inserts are inserted into housings made on this substrate, to form an equipped sacrificial substrate, which is provided with the resists necessary to obtain, by means of an electroforming process, a bare electroformed component, with deposition of material on this substrate, acting as a core to form this electroformed shell, and on each accessible surface of each insert to secure the insert to this electroformed shell; then this sacrificial substrate is destroyed and all of these resists are removed.

A timepiece includes a base, a case, a frame, and a gimbal coupling mechanism. The case holds a time display. The case is pivotably connected to the frame for rotation about a first axis. The frame is pivotably connected to the base for rotation about a second axis between an extended and a retracted position. The frame form a two-axis gimbal supporting the case. The gimbal coupling mechanism operably couples the frame and the case whereby rotation of the frame from the retracted position to the extended position then back to the retracted position rotates the case about the first axis to facilitate flipping of the case so as to selectively hide or show the time display.

A Dewar device is for mechanical and/or functional components of a watch. The device is provided with a wristlet and a casing. The casing includes a chamber in which a case of the watch is capable of being arranged in a removable manner, and a device for reversible fastening by magnetic levitation of the watch case in the chamber configuring a separation between the case and the set of the elements of the casing forming the chamber.
