  • thaumatrope comprises at least two patterns on the front and back of a pivoting mobile, such as a token stretched between two threads, each of these two patterns contains only part of the information, of this done when the mobile is stopped, the observer cannot see the entire image, whereas, when the mobile is set in motion, for example by twisting then pulling the two wires, a complete image resulting from the superposition of the two patterns is then revealed to the observer; for example a bird in a cage results from the visual superposition of a first pattern of empty cage and of a second pattern of free bird.
  • the invention proposes to create a visual animation which operates continuously, as long as the timepiece (in particular a watch) operates, without requiring other energy, and without altering its chronometric performance.
  • the invention also endeavors, in the particular case of the watch, not to increase its thickness, and not to weigh it down, and to modify its thickness as little as possible.
  • mechanism the implementation of the invention is possible on any existing mechanical watch.

  • the mobile display 7 is an idle inertia wheel, which is directly engaged with the escape wheel, and which is included in the escape mechanism 6.
  • Such an inertia wheel does not have kinematic function, and meshes only with the escape wheel, its function is to limit the sensitivity of the oscillator to the accelerations carried, it preferably has the same inertia as the escape wheel but it can be both thinner and lighter than the latter, which allows a larger display surface of the 8 animation patterns, and on a larger diameter than that of the escape wheel, of which it has the same rhythm jerky.

  • the patterns 8 are diffractive patterns which form an image on a surface remote from the timepiece 1, for example by diffraction of a laser beam.
  • a particularly advantageous optical variant consists in the use of “FOP” or “plastic optical fiber”, which relates to the grouping of optical fibers in a bundle or a ribbon.
