A timepiece incudes a crown (4) housed in a cavity (10) provided in the case and open towards the outside, such as a cavity (10) in the side wall of the case (1) of a wristwatch, in the rest position of the crown (4). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (5). The knurling-roller (5) is coupled to a tube (15) wherein is inserted a crown body (18) integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (18). The tube displaces the crown in an axial direction without rotating the crown around its central axis (6). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller (5) without having to manually pull the crown outwards.

A control device (1) for a timepiece has: - a body (4) intended to be mounted to be able to rotate about an axis of rotation (X) in a case middle (2) of a timepiece in order to drive a mechanism of the timepiece, and: - a crown head (5) movable in translation with respect to the body, parallel to the axis of rotation, between a first position and a second position. The body has a first coupling means (46) and the crown head has a second coupling means (53), arranged so that when the crown head is in its first position, the body and the crown head are uncoupled, and when the crown head is in its second position, the body and the crown head are coupled, the control device further comprising a locking element (6), a first formation (47A) and a second formation (47B), the locking element being able to cooperate with the first formation to stabilize the crown head in its first position, and with the second formation to stabilize the crown head in its second position, the locking element being integral with or fixed to the crown head and the first and second formations being integral with or fixed to the body, or the locking element being integral with or fixed to the body and the first and second formations being integral with or fixed to the crown head.

An external watch control device (100) including a crown (1) carrying a first barrel (2) screwed onto a tube (4), coaxially guiding a second barrel (3) includes a driver (7), the first barrel (2) and the second barrel (3) including opposing unidirectional toothing (8; 9), the tube (4) containing a spring (11) tending to move the first barrel (2) away from the driver (7), the unidirectional toothing (8; 9) are at maximum distance when the crown (1) is completely screwed onto the tube (4), and in meshing position when the crown (1) is completely unscrewed, the cooperation between the unidirectional toothing (8; 9) allowing the rotation of the first barrel (3) in a first single direction of rotation of the crown (1), and preventing it in the opposite direction against the spring (11) in the manner of a pawl.

The stem-crown of a water-resistant watch case includes a tubular stem inserted into a tubular opening of a middle part of the watch case, and a crown including a first portion connected in part to the stem and a second handling portion. The first portion includes an annular contact surface inclined at less than 90° with respect to a longitudinal central axis of the stem-crown starting from the first portion towards the outside of the second portion. In a rest position, the first portion is in contact against an annular receiving surface of the middle part of complementary shape to one end of the tubular opening towards the outside. The crown further includes a washer under a bearing part of the first portion and contacting the stem, being configured to bear in an annular slot of the middle part between the tubular opening and the annular receiving surface.

This relates to a sealing device (100) for a watch (200) configured to be inserted into a primary space (201) comprised in a middle part (210). Said sealing device (100) comprising at least one insertion organ (110) configured to be inserted into said primary space (201), at least one first sealing elements set (120) configured to seal said primary space (201) between said middle part (210) and said at least one insertion organ (110), and at least one second sealing elements set (140) configured to seal a secondary space (131) between at least one drive organ (130) and said at least one insertion organ (110).

A watch case, including an orientable screwed crown including axially movable, a subassembly including a setting body including a pattern, a tube suitable for being axially inserted into a hole of the case and including an axial indexing profile engaging complementarily with a complementary axial indexing profile of the hole, and the indexing profile is a cone of apex angle less than 15°, arranged to engage by friction with the complementary indexing profile of the hole.

A screw-down orientable crown (200) for watch case (100), including a tube (11) that can be axially inserted into a case housing (90), and a handling body (1) including a pattern (19) and a relief (15) extending axially and, in the coupled position, cooperating for indexing the pattern (19) relative to the case (100) with a complementary relief (55) that a fixed pipe (5) includes which is pushed back from the body (1) by a spring (12), and including an axial stop (3) fixed to the body (1) to axially trap the fixed pipe (5) with a stroke corresponding to the deformation of the spring (12) to enable the disconnection, by a compression of the body (1), between the relief (15) and the complementary relief (55), which relief (15) is carried by a trunnion (4) integral with the body (1) and which is inside the fixed pipe (5).

A timepiece incudes a crown (4) housed in a cavity (10) provided in the case and open towards the outside, such as a cavity (10) in the side wall of the case (1) of a wristwatch, in the rest position of the crown (4). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (5). The knurling-roller (5) is coupled to a tube (15) wherein is inserted a crown body (18) integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (18). The tube displaces the crown in an axial direction without rotating the crown around its central axis (6). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller (5) without having to manually pull the crown outwards.

A watch includes: a crown including a head portion and a shaft portion; a stem pipe including a first surface that includes an insertion hole through which the shaft portion is inserted and has a distance from a surface of the shaft portion as a first distance in cross-sectional view, and a second surface that is provided at a position closer to an end portion of the insertion hole than the first surface and has a distance from the surface of the shaft portion as a second distance larger than the first distance; a packing disposed between the surface of the shaft portion and the first surface; and a metal ring that is disposed between the surface of the shaft portion and the second surface and is in contact with the packing.
