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

External control mechanism for a timepiece

A control device () for a horological movement, including a first part including a sliding guide tube () intended to be fixed relative to the horological movement, and a second movable part () slidably guided by the guide tube in an axial direction, relative to the first part, between an active position wherein it is able to be integral, by means of an adjustment rod (), with a component of the horological movement, and an inactive position wherein the adjustment rod is intended to release the component of the horological movement. The second part includes a head () covering a reversible elastic casing module () fixed to the adjustment rod and arranged so as to occupy a rest state when the second part occupies the active and inactive positions and being urged by the guide tube when the second part moves between these positions.

Device for controlling a horological movement with tactile feedback and timepiece, in particular a watch, comprising such a device

A timepiece incudes a crown () housed in a cavity () provided in the case and open towards the outside, such as a cavity () in the side wall of the case () of a wristwatch, in the rest position of the crown (). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (). The knurling-roller () is coupled to a tube () wherein is inserted a crown body () 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 (). The tube displaces the crown in an axial direction without rotating the crown around its central axis (). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller () without having to manually pull the crown outwards.

Device for controlling a timepiece

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