A method for manufacturing a decorative article (2) including the following steps of: making a blank by injection moulding a material comprising a metallic material, machining and/or polishing the blank to form a product, and forming the product to print a raised or recessed relief pattern (3) on part of the surface of the product, the product with the pattern (3) forming the decorative article. Also, a decorative article, notably an external timepiece part made of a sintered material having on part of its surface a raised or recessed relief pattern (3) made by a forming process. Preferably, the sintered material is a grade 5 titanium alloy (Ti6V4Al) or a stainless steel.

A device for controlling the functions of a watch, which includes a crown connected to a stem, an optical action system actuated in one position of the stem from among three possible positions to determine the direction of rotation of the stem, and an electronic mechanical arrangement for controlling the functions. A guide element can rotate on a support and which has a rounded end in an annular groove of the stem to be driven in rotation, and a selection part can rotate on the support above the annular groove to be driven in rotation. The selection part includes at least one contactor for contacting a first electrical terminal on a printed circuit board in a first position of the stem, with no electrical contact in a second position of the stem, and for contacting a second electrical terminal in a third position of the stem.

A non-magnetic watch component (1) comprising a substrate (4) made of a copper alloy, wherein at least one part of the substrate (4) has a surface layer (5) including CuxTi.sub.y intermetallics, and a method for manufacturing this watch component.

A timepiece which provides a tactile feel in a simple structure and which can suppress inadvertent rotation of a driving crown is to be provided. A wristwatch includes an elastic material winding stem pipe protruding on the outer side of a case and a distal end portion of which is capable of elastic deformation in a radial direction; a shaft member of a driving crown rotatably inserted into the elastic material winding stem pipe; protrusions formed on the peripheral surface of the driving crown; and trough portions formed in the peripheral surface of the elastic material winding stem pipe and configured to be engaged with the protrusions.

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.

A timepiece case, including a seat which guides inside it a push-piece for supplying energy, including a control member which can be operated with pressure against resilient return device and which is integral with driving device, the push-piece or the case including a flat cam track, the case or the push-piece including a pivot about which an arm carrying a pin following the profile of this track pivots, which track includes elbows directed towards the pivot and defining stable positions of the pin and ramps arranged so that any pressure applied on the control member when it is in the rest position causes the pin to come out of its stable position and to travel, under the action of the resilient return device, towards another stable position.

A control crown for a timepiece, capable of cooperating, in order to maneuver a control rod, with a middle including a recess along an axis receiving a tube included in the crown, which includes a crown body capable of rotating covering both the rod and the tube, which includes a hollow to allow the rod to pass and/or be guided in rotation, the crown includes a closing cap fastened to the tube in a fixed angular position relative to the middle by the cooperation between indexing device of the tube and complementary indexing device of the closing cap, to axially enclose the crown body between the middle and the closing cap.

A crown/pusher including a tube attached to a watch case, a recessed head integral with a stem which is movable with respect to the tube and defines an axis, the recessed head being mounted to move in rotation and in translation respectively around and along the axis of the stem, a return spring disposed around the stem, the crown/pusher includes a cage housing the spring, the cage being traversed by the stem and including an upper part integral with the recessed head and a lower part freely mounted with respect to the recessed head, the upper part cooperating with the lower part in order to drive the lower part in its rotational movement and in order to move in translation along the axis with respect to the lower part, the spring being compressed inside the cage in order to be driven in rotation with the cage.

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) trapped therebetween, and, in the disconnected position by compression of the spring (12) remaining axially distant from the complementary relief (55) and without cooperation therewith, and including an axial stop means (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).
