The present disclosure relates to a case assembly for a ceramic timepiece. The case assembly is configured to accommodate a movement which includes a first groove, defining an inner periphery of a first side of the casing. The first groove accommodates a glass of the timepiece, within a thickness of the casing. Further one or more provisions are provided in a second side of the casing, where each of the one or more provisions is configured to receive an adapter. Each of the adapter receives a fastening member, for securing a back plate of the timepiece within the height of the casing. A dial including a pair of projections extending outwardly from two opposing portions of an outer periphery of the casing is provided to receive a strap of the timepiece. The configuration of the dial helps in reducing the thickness of the timepiece.
