• This second central piece 2 carries all the members, bridge and wheels or wheels of a clockwork movement is illustrated alone in FIGS. 3 and 4 and carrying all the members, the bridge and the wheels or the moving wheels of the clockwork movement in FIG. .
• This second central piece 2 is perforated in the illustrated example and has the shape of a skeleton piece.
• This second central piece 2 has an outer periphery 2.1 whose shape and dimensions generally correspond to the shape and dimensions of the inner periphery 1 .3 of the opening 1 .2 of the first outer part 1 of the plate.
• This second central part 2 of the plate can thus be introduced, preferably exactly and virtually without play, into the central opening 1 .2 of this first outer part 1 of the plate and these two parts 1, 2 are secured by welding , bonding or any other means for forming a plate 1, 2 in one piece or pseudo monoblock as illustrated in Figures 5 and 6.
• Some moving components of the clockwork movement rotated on the second central part 2 extend into the recesses 1, 4 of the first outer part 1.
• the first piece 1 and the second central piece 2 being permanently fixed to one another, they form a plate in one piece or pseudo monobloc movement or plate supporting the various organs of the movement.
• the plate 1, 2, once assembled, can not be separated into two parts, so that the movement can be removed from the watch case in one piece without having to be disassembled.
• the outer periphery 2.1 of the second central part 2 can be in contact and permanently attached to the first outer part 1.
• the outer periphery 2.1 may comprise three or four tabs which extend radially towards the first outer part 1 and which fit into the inner periphery 1 .3 of the opening 1, 2 of the first outer part 1.
• this second central part 2 serves as a support for all the elements, bodies, bridge, wheels and mobiles of the watch movement. Once mounted on this second central piece 2, some of these elements of the watch movement overflow the outer periphery 2.1 of the second central piece 2 of the plate and are received in one of the recesses 1 .4 made in the first piece outer 1 of the plate.
• the plate of the movement is achieved by the final attachment of the first part 1 and the second part 2 thus forming a unitary assembly pseudo monoblock supporting or housing the various organs of the movement. It is also thanks to the fact that these two parts 1, 2 form a unitary assembly that the movement can be removed from its box without being disassembled.
• the first outer part 1 of the turntable is not a simple circle transparent casing since it has recesses 1 .4 housing or giving passage to certain mobile watch movement.
• the outer periphery of this first outer part 1 serves as a casing ring to fix the movement on the watch case.
• This first piece 1 of the motion plate has two functions.
• Figure 6 illustrates the two outer parts 1 and 2 central platinum assembled to each other so as to form a set in one piece is pseudo monobloc.
• FIG. 8 illustrates the one-piece plate 1, 2 provided with elements of the clockwork movement pivoted on the second central part 2 of the plate and extending partially into the recesses 1, 4 of the first outer part of this one-piece plate.
• Figure 9 illustrates in section a watch provided with a movement
• timepiece comprising a one-piece plate 1, 2 according to the invention.
• This watch comprises a box, formed in the illustrated example, of a caseband 3, a base plate 4, a window 5 and an upper window 6.
• the one-piece plate 1, 2 carrying the watch movement is placed in the watch case, the first outer part 1 rests via first o-rings 7 on the middle and the upper face of this first outer part 1 the platen is supported by means of second o-ring seals 8 against the underside of the bezel 5.

• the second central part 2 of the plate could be full, not skeletonized.
• the fixing of the first outer part 1 of the monoblock plate 1, 2 on the watch case can be carried out in a known manner, different from that illustrated and described.
• the plate described in two pieces 1, 2 made permanently integral with each other to form a one-piece assembly allows to have a first transparent outer part to achieve certain optical and aesthetic effects on the watch and a second opaque central piece that can be metallic for the traditional assembly of the bridges, and the pivoting of the moving parts and wheels of a clockwork movement.
• the watch movement platen comprises two parts assembled so as to form a one-piece assembly.
• a first outer part having a central opening in which is secured the second central part.
• the shape of the first outer part corresponds to the shape of a watch case in which it must be fixed by means of fastening means that it comprises.
• the second central part presents all the machining, holes, threads, holes, etc. to allow the assembly and pivoting of the elements, bodies, bridges, wheels, mobiles, rockers, springs, etc. that includes a clockwork movement which this second central part forms the support or the base.
• This second central piece is thus arranged to serve as a support for the movement timepiece but has a small area, less than that occupied by the movable members of the movement, since at least some of these movable members of the movement are housed or move in the recesses 1 .4 made in the first outer part 1 of the monoblock platinum.
• the first outer piece is made of a transparent material such as sapphire while the second central piece is opaque and preferably metallic.
• the periphery of the second central piece has a shape and dimensions corresponding to a central opening made in the first outer part so as to be housed without play.
