Definitions

• the present invention relates to the field of watchmaking, more particularly to a synergetic compensation device for a so-called mysterious watch comprising a plurality of transparent disks coaxially mounted and rotated by means of mounted drive members. invisible way in the case ring.
• Transparent watches generally called mysterious watches, whose movement of the hands is transmitted through transparent toothed discs are already part of the state of the art.
• the patent CH639812 as well as the document EP0673519 describe such devices.
• EP0673519 discloses a transparent watch provided with a second hand, a minute hand and an hour hand whose movement is distributed by means of transparent discs driven by one or more motors confined in the case ring of the watch.
• This type of watch can be subject to walking gaps that can be caused by a sudden movement of the wrist. Indeed, such a movement can accelerate or slow down the different disks and therefore alter the accuracy of the watch.
• the object of the present invention is to provide a so-called mysterious watch comprising a device intended to compensate for the synergistic effects that may be caused by the movement of the wrist.
• a mysterious watch comprising a seconds tree, a minute gun and an hour gun driven respectively by a second disc, a minute disc and a disc of the minutes. arranged hours coaxially between the dial and the bottom of the watch case.
• Said dial and the bottom of the watch case and said discs are at least partially transparent. These have a toothing on their outer perimeter in order to be driven by transmission members confined invisibly in the ring of the so-called mysterious watch case.
• This comprises a device comprising a disk called "false seconds", a double reference and at least one intermediate wheel.
• the disk says “false seconds” is freely adjusted around the perimeter of the hours barrel and driven by the double return that transmits the speed of rotation of the second disc.
• the intermediate wheel provides a direction of rotation of the disc "false seconds” contrary to the second disc.
• FIG. 1 shows a dial side view of a so-called mysterious watch according to the invention comprising two partial views respectively at 2 hours and 5 hours.
• FIG. 2 represents a detailed view of the compensation device located at 2 o'clock in the ring of the watch case of FIG. 1.
• FIG. 3 represents a sectional view along the line B-B of FIG. 2.
• the so-called mysterious watch (1) is a wristwatch which comprises a second disc (5) integral with the shaft (2), a disc (6) of the minutes integral with the gun (3) minutes and a disc (7) hours integral with the barrel (4) hours ( Figure 4).
• a device comprising a disk (10)
• this disc is driven by the double return (12).
• This is arranged so that the intermediate gear (14) can transmit the movement of the disk (5) seconds to the lower return (18) of the double return (12).
• the upper return (19) thereof transmits the speed of rotation of the disc (5) seconds to the disk of "false seconds".
• the rotation thereof is contrary to the rotation of the disk (5) seconds.
• a stationary intermediate disc (13) ( Figure 4) is arranged between the seconds disc (5) and the minute disc (6) to support the minutes disc (6), hours (7), and false seconds. (10) as well as the shaft (2) and the barrels (3, 4).
• a spacing washer (20) is arranged on the barrel (4) hours between the dial (8) and the disk (10) of "false seconds" in order to prevent a vertical movement of movement in the watch case (1) and on the other hand to ensure a planar rotation of the disc (10) of the "false seconds".
• the different discs (5, 6, 7, 10 and 13) as well as the dial (8) and the bottom (9) of the watch case (1) are transparent and sapphire.
• the mass and the diameter of the disc (5) of the seconds and the disc (10) of the "false seconds" are identical so that the moment of inertia of the two discs (5, 10) is identical.
• At least one rotating transparent part and / or at least one non-rotating transparent part comprises figures in order to create patterns of preference. animated.
• a mysterious watch (1) may comprise a first figure engraved on the dial (8), a second pattern engraved on the disk (5) seconds and a third pattern engraved on the disc (10) of "false seconds”.
