Modes for Carrying Out the Invention

[0011] Figures 1 to 5 show a watch assembly 10, particularly for a wristwatch. Such an assembly 10 may be a wristwatch and is included in this wristwatch. In this assembly 10, a display module 1 is arranged within / on a plate 2 of the watch movement of this wristwatch. Thus, such an assembly 10 comprises this display module 1 and plate 2. Such a display module is, in a non-limiting and non-restrictive manner, - the high-speed correction selector indicator of this wristwatch, or - the date display, and it should be noted.

[0012] In this configuration, the display module 1 comprises at least one display component 4, a protection element 3, and a pivoting element 5. The display component 4 is a movable, preferably rotatable timepiece that is directly involved in the selection, presentation, and / or display of watch information. In other words, this component 4 can be provided with a graphic representation that is particularly involved in this selection, or, for example, can be configured to perform this selection by its shape, or this component 4 is provided with at least one graphic representation corresponding to the watch information to be displayed / presented and is thus selected for this purpose. This component 4 can be a dial or a hand, but is not limited thereto. In this embodiment, this component 4 can be a component that is rotatable about its rotation axis A, for example, in this case, a movable dial or a movable hand. It should be noted that in this configuration, such a display component 4 is driven by such a rotational movement by a pivoting element 5 such as a pinion that is kinematically connected to the mechanism of the watch movement of the wristwatch. Such a pivoting element 5 passes through a passage zone 16 of the plate 2 that connects the display component 4 to this mechanism. It should be noted that such a mechanism can be configured to implement a high-speed correction selector indicator.

[0013] As already mentioned, this display component 4 can be a dial, as shown in FIGS. 1 to 5. In this configuration, this dial can be fixed by driving its mounting area 21 at the first end of the pivoting element 5 that forms the pivot. It should be noted that the second end of this pivoting element 5 also forms a pivot and can be attached to a bearing, particularly an impact-absorbing bearing.

[0014] Such a dial has a visible face 8 with at least one graphic representation used for the selection, presentation, and / or display of timekeeping information. It should be noted that when this component 4 is a hand, the hand is also driven at this pivot of the pivoting element 5.

[0015] In this display module 1, the protective element 3, also referred to as a cover, has an opening recess delimited by a peripheral wall 15 and a bottom that is completely or partially transparent. This recess is intended, in particular, to house or receive the display component 4. As shown with reference to FIGS. 1 to 3, this protective element 3 is composed of two parts 7a, 7b, - The first part 7a is essentially annular in shape and has opposing openings of substantially the same cross-section, which are interconnected by the said peripheral wall 15, - The second part 7b is completely or partially transparent and is intended to be attached to one of the two openings so as to form the bottom of the recess defined in the protective element 3.

[0016] More specifically, this second part 7b can be made of crystal and is attached to the first opening of the first part 7a. It is understood that this first opening is specifically configured to be assembled with such a second part 7b.

[0017] Therefore, in this protective element 3, this second part 7b is - By having a graphic representation corresponding to the clock information, it is overall / fully transparent, and the selection and / or presentation of one of these information items is performed by a display component 4 such as a hand. - By having a graphic representation corresponding to the clock information, it is overall / fully transparent, and the selection and / or presentation of one of these information items is performed by a display component 4 such as a dial, and its visible surface 8 has a graphic representation such as an arrow or a hand representation. - By having a graphic representation such as an arrow or a hand representation to select and / or present one information item from the clock information included in the graphic representation existing on the visible surface 8 of a display component 4 such as a dial, it is overall / fully transparent. - It is transparent and partially transparent by being completely opaque except for a part of this portion 7b that selects and / or presents information from the clock information included in the graphic representation existing on the visible surface 8 of a display component 4 such as a dial, like an opening. - It is understood to be partially transparent by being completely opaque except for the opening made in this portion 7b that selects and / or presents information from the clock information included in the graphic representation existing on the visible surface 8 of a display component 4 such as a dial, like an opening.

[0018] In this first portion 7a, it should be noted that the second opening defined at the end of the peripheral wall 15 of this portion has an edge 19 of this portion 7a separated by this end.

[0019] In this configuration, such a first part 7a comprises tabs 6a, 6b that serve to arrange the display module 1 within / on the plate 2. In this embodiment of the module 1, in a non-exhaustive and non-limiting manner, there are two such tabs 6a, 6b. These tabs 6a, 6b are each an extension of the peripheral wall 15 of this first part 7a and extend perpendicularly in a direction parallel or substantially parallel to the axis of rotation A when the protective element 3 is attached to the plate 2. In this context, these tabs 6a, 6b are understood to be extensions of this peripheral wall 15 starting from the edge 19 of this first part 7a.

[0020] Furthermore, such a first part 7a further comprises a support element 20 provided with a contact surface 18 intended to abut against the plate 2 when the display module 1 is arranged within the plate 2. Similar to the tabs 6a, 6b of the first part 7a, the support element 20 is also an extension of the peripheral wall 15. Such a support element 20 comprises an element 6c for positioning the display module 1 relative to the plate 2. This positioning element 6c is a protrusion or raised portion included in the contact surface 18 of the support element 20. This positioning element 6c is an extension of the support element 20.

[0021] In this assembly 10, the plate 2 preferably has a general shape similar to that of a watch case. This plate 2 comprises an upper surface 11a and a lower surface 11b, and a side wall 11c that joins these surfaces 11a, 11b together. Such upper surface 11a and lower surface 11b are in planes parallel or substantially parallel to each other.

[0022] Such a plate 2 comprises cavities 9a, 9b configured to receive the tabs 6a, 6b of the protective element 3 and, by extension, the tabs 6a, 6b of the display module 1. Each cavity 9a, 9b comprises a housing that opens onto the upper surface 11a. In other words, the cavities 9a, 9b comprise passage openings 13a, 13b within the housing included in this upper surface 11a of the plate 2.

[0023] The housing of these cavities 9a, 9b extends in the thickness direction of the plate 2 in a direction perpendicular or substantially perpendicular to the upper surface 11a. It should be noted that this housing extends towards the lower surface 11b of the plate 2 in a direction parallel to the rotation axis A of the display component 4. As shown with reference to FIG. 1, these cavities 9a, 9b can have a rectangular shape. In other words, the cross-section of the housing can have this rectangular shape.

[0024] This plate 2 further includes through-holes 14a, 14b for each of the cavities 9a, 9b. These through-holes 14a, 14b have two openings, one opening leading to the housing of this cavity 9a, 9b and the other opening leading to the outer surface of the side wall 11c of the plate 2. These through-holes 14a, 14b include recesses defined between these openings, and fastening elements 17a, 17b for fixing tabs 6a, 6b positioned within the housing of the cavities 9a, 9b can be arranged in these recesses. In other words, this recess is configured to receive fastening elements 17a, 17b with one end protruding into the housing in order to contact the contact surface 18 of the tabs 6a, 6b positioned facing the second opening of this hole 14a, 14b for fixing the tabs 6a, 6b to this housing. In such a configuration, this recess is configured such that when the fastening elements 17a, 17b hold the tabs 6a, 6b within the housing, the other end of the fastening elements 17a, 17b does not protrude from the outer surface of the side wall 11c. These through-holes 14a, 14b extend linearly in a direction perpendicular or substantially perpendicular to the direction of the cavities 9a, 9b in the thickness of the plate 2, from the side wall 11c towards the housing. In other words, the central axes B, C of these through-holes 14a, 14b are perpendicular or substantially perpendicular to the direction of the rotation axis A. Such through-holes 14a, 14b have a length longer than that of the fastening elements 17a, 17b in order to hide the fastening elements 17a, 17b within the plate 2. It should be noted that this hole 14a, 14b can be tapped to cooperate with fastening elements 17a, 17b such as screws.

[0025] On the one hand, this plate 2 further comprises an orifice 12 for receiving the positioning element 6c. Such an orifice 12 has a shape complementary to the shape of the positioning element 6c.

[0026] In this assembly 10, the display module 1, in particular, - fixes the tabs 6a, 6b of the protection element 3 to the cavities 9a, 9b of the plate 2 by means of fastening elements 17a, 17b that abut against the contact surfaces 18 of the tabs 6a, 6b, - abuts the protection element 3 against the upper surface 11a of the plate 2 via its support element 20, - holds the protection element 3 in the mounting position on / within the plate 2 by placing the positioning element 6c in the orifice 12 within the plate 2, - holds the display component 4 by means of the pivoting element 5 in the recess of the protection element 3, whereby it is arranged on the plate 2.
