The invention concerns a watchcomprising a watch case, the watch casecontaining a watch movementand two dials. The watchfurther includes a casing ringarranged inside the watch case, the watch movementbeing mounted in the casing ringso as to be suspended in a cantilever arrangement inside the watch case, said casing ringsupporting the two dials

Watch comprising a watch case provided with two dials

A dial for a timepiece, such as a watch, includes at least one three-dimensional decoration offset away from a base plate which forms part of the dial. The decoration is mounted on the base plate by an assembly of elements including a fixing screw, a support bar including a proximal end secured to the base plate by the fixing screw and a distal end attached to a first point of the lower surface of the decoration, a support foot including a proximal end held in a fixed position in the plate of the base plate and a distal end attached to a second point of the lower surface of the decoration, and a spacer which forms a lateral connection between the fixing screw and the support foot, the spacer being secured with the support bar to the base plate by the fixing screw.

Timepiece dial provided with a three-dimensional decoration

A timepiece, in particular a pocket watch, that includes a case delimited by a middle, the timepiece further including at least one cover covering a device for displaying information, as well as a device for controlling the opening of the at least one cover, this control device including a ring pendant and a command transmission member, the ring pendant arranged such that it is pushed in a rectilinear manner a first time towards the middle into a first abutment position, then such that it is rotated in a first direction into a second abutment position, then such that it is pushed in a rectilinear manner a second time towards the middle so as to cause the cover to open by an action on the command transmission member.

Timepiece, in particular a pocket watch, equipped with at least one cover

Watch comprising a movement with an axially and rotationally movable main stem, and a control mechanism for the remote control of the main stem which comprises a secondary stem operable by a user and guided in rotation by guide means of a plate, and axial stop means for a secondary pinion integral in rotation with the secondary stem, and a transmission train meshed with the secondary pinion to transmit any rotation of the secondary pinion to the main stem, and further comprises an articulated connection, arranged to transmit any axial motion of the secondary stem to the main stem.

Remote control mechanism for timepieces

A dial assembly for a timepiece includes a base plate on which feet are fixed. The dial assembly supports a three-dimensional decoration which includes at least one offset element at a remove from the base plate and fixed to the base plate through at least one foot. The at least one offset element includes at least one bush provided to be pressed in on an upper support abutting on a shoulder of this foot. The dial assembly includes a removable fitting which is used for pressing in all the bushes of the dial assembly. The dial assembly includes, opposite a lower support of each foot, a support pin of this lower support.

Watch dial with three-dimensional decoration, and assembly tools

A timepiece has a portion of its case body capable of being removed from the rest of the case body. The removable portion bears an interchangeable dial plate. The device is configured in such a manner that the dial plate never serves as a stopping abutment when it is inserted in the timepiece. A closure device allows the interchangeable dial to be suitably fastened to the watch.
