  • Patent number: 10571864
    Abstract: 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.

  • Patent number: 7035171
    Abstract: 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.
