Dependent claims

A dial (10) comprising:

a support plate (12);
an external parts plate (11) visible for a user, said external parts plate (11) resting on a bearing surface (120) of the support plate (12) on which the external parts plate is superimposed;
and
peripheral and central fastening members respectively provided on the support plate and the external parts plate, the external parts plate (11) and the support plate (12) being fastened to one another at their periphery by the cooperation of the peripheral fastening members, and being fastened to one another at their centre by the cooperation of the central fastening members,
wherein the peripheral fastening members of the external parts plate (11) and of the support plate (12) are configured to cooperate with each other in a removable manner, and the central fastening members of the external parts plate (11) and of the support plate (12) are configured to cooperate with each other in a removable manner, so as to be able to disconnect said external parts (11) and support (12) plates from one another without damaging the external parts plate, and
wherein the peripheral fastening members of the external parts plate (11) include at least one radial tab (112), and wherein the peripheral fastening members of the support plate (12) include at least one catch (122) forming a notch (123), said at least one catch (122) being configured so that the notch (123) receives in insertion said at least one radial tab (112),
wherein said at least one catch (122) includes an end portion (1220) arranged parallel to the bearing surface (120) in a first radial direction, and
wherein the peripheral fastening members of the support plate (12) include a pin (125) extending from the bearing surface (120) of the support plate (12) and an elastic bracket (126) extending in a second radial direction opposite to the first radial direction and is elbowed with respect to said bearing surface (120), said elastic bracket (126) being separated from said pin (125) by a space forming an interstice into which a radial protrusion (113) of the external parts plate (11) is inserted, said elastic bracket (126) being capable of being deformed elastically by said radial protrusion (113) during its insertion into the interstice.
