At the time of international Living room of the clock industry of prestige which took place last on December 7 and 9 with the Carrousel from Louvre in Paris, Richard Thousand, Bvlgari, Greubel Forsey, Key Van & Arpels, Hysek, Maurice Lacroix, Chaumet or Bedat & Co presented at a public impassioned their last highly technical jewels, designed for the majority in limited editions.

      The contemporary watches reach a true degree of technical complexity as well as an esthetics indomitable. Able to resist deteriorations of time and the whims of the tendencies, the watches curl the extreme perfection. Indeed, the clock industry is the more active sector as regards technical progress and innovation. 120 patents were deposited in 2005, only for the Swiss clock industry.

In this prestigious search with the extreme complications, the clock and watch makers seek to impose their supremacy.       The most outstanding creation of the living room returns to Richard Thousand with its planet gear tellurium whose design required more than seven years. The planet gear-tellurium of Richard Thousand is a single object.
It comprises a great number of indications and astronomical representations of an extreme precision. The conceptual choices must be effective, each function should not weaken or penalize another, and the coherence of operation of the subsets represents an immense difficulty calculation realization.

      Thus, seven years will have been necessary for the design, the development and the manufacture of this planet gear-tellurium.
      The major difficulty in the design of a planet gear-tellurium lies in the total control of calculations of gears and the planetary wheels. It proves to be a major and exceptional part, more particularly thanks to the existence of a single combination Planet gear-tellurium/perpetual day of the month, exhaust with relaxation, and beam with variable inertia. This object is, contrary to the traditional planet gears, much nearer to the high clock industry of small volume than of the peddler.

      First of all, the diameter of the ground, which for practical and aesthetic reasons, was notably enlarged, (the ground is actually 109 times smaller than the sun) a good vision of the continents allows, even of the countries. The indications (date, equation of time, horoscopes) are represented in a readable and coherent way, and separately of the plan of rotation of planets. The reassembly of planet gear-tellurium is carried out by a system with lever, and reserves it of walk is 15 days.

      The movement of planet gear-tellurium is equipped with an exhaust with relaxation much more powerful than the lever escapement, because it disturbs less the regulating body (beam).
      The adjustment of the advance and the delay is done on the beam with variable inertia, by the means of the regulating screws. This type of beam represents the last word and guarantees a greater reliability as well as better chronometric results.
The spring of barrel is of Tensator type, and provides a more constant couple, essential element of the performance.
      A system of arrogate on the barrel ensures a better beach of use within the competence of barrel.
