Abstract: A watch case comprising: a middle (3), a first tube (1) provided with first indexing elements (1a), a control crown (C) including: a cap (4) having a distinctive sign (S) on a front face (4?), and a bush (5) intended to be connected to the movement of the watch, a second tube (2) adapted to be fastened to the middle (3) and to receive the bush (5), the control crown (C) and the first tube (1) including respective screwing elements (1b,4b) for screwing them together. Second indexing elements (3a,3a?,3a?) fastened to the middle (3) are provided to cooperate with the first indexing elements (1a) of the first tube (1). The first tube (1) and the second tube (2) are conformed so that fastening the second tube (2) to the middle (3) ensures axial immobilization of the first tube (1) relative to the middle (3).

Abstract: A timepiece component (1) for a watch case, notably a bezel, comprising an axis (A), a first ring (10), a second ring (11) and a connecting element (12) for connecting the first and second rings, the connecting element being elastic and positioned between the first and second rings, the first ring and/or the second ring comprising an element (31) for retention on the rest of a watch case (200), particularly on a watch middle (4).

Abstract: This watch case comprises a middle (1), a tube (3, 23), which is secured to the middle (1) and is provided with a thread, a control crown (C) which is provided with a thread screwed onto the tube (3, 23), the control crown (C) having an external part (10, 20) that has a distinctive mark (S) that is visible from the outside and an internal part (2, 24) housed inside the external part (10, 20) and clamping means (11) for axially holding said external part (10, 20) and said internal part (2, 24) in an angular position determined with respect to the longitudinal axis of said tube. The internal part (2, 24) has first angular indexing means (2a, 24a), the external part (10, 20) having second angular indexing means (10a, 20a), these indexing means being shaped so as to engage axially in one another.

Abstract: The present invention concerns a wristwatch type of watch. More specifically, the watch comprises a display (11), an electronic circuit (12) controlling the display, a time set stem (13), and at least two electrical contact elements (14, 14″). The time set stem (13) can be placed in different axial positions and the stem comprises a crown (16) accessible from outside the watch and a helicoidal zone (19) which may have three helicoidal elements (20, 20′, 20″). When the time set stem is placed in a position such that the contact elements (14, 14″) are facing the helicoidal zone (19), rotating the time set stem causes an electrical connection on the electronic circuit (12) to alternately open and close. This generates at least two electrical impulse signals which are transmitted to the electronic control circuit. These signals are used to regulate different watch functions, such as time correction or controlling the time belt or the date.
