  • the middle 10c and the back 10b of the case 4 can together form a one-piece piece, said one-piece piece defining an opening opposite the bottom 10b which is capable of being closed by the glass 10a and this, in a reversible and sealed manner.
  • the middle 10c and the crystal 10a of the case 4 of the watch 3 can together form a one-piece piece, said one-piece piece defining an opening opposite the glass 10a which is capable of being closed by the bottom 10b and this, also in a reversible and sealed manner.
  • the caseband 10c and the back 10b are preferably made in a non-limiting and non-exhaustive manner from a metallic material, from glass or from thermosetting or thermoplastic polymer resins reinforced with carbon or glass fibers or even from ceramic materials. It will be noted that when caseband 10c and back 10b are transparent or semi-transparent, for example being made of glass, peripheral wall 12 of caseband 10c and the inner face of back 10b can be coated with a metallic or similar reflective coating, such as for example a layer of silver.
  • the device 1 can comprise an interferometric filter arranged on an overall outer face of the case 4, namely on an outer peripheral wall of the middle part 10c and/or of the outer faces of the crystal 10a and of the bottom 10b of this box 6 of shows 3.
  • This interferometric filter can be a grid or a lattice forming a coating on this external overall face of the case 4.
  • This grid or lattice has a mesh whose dimensions are such that they only allow certain predetermined wavelengths to pass of the electromagnetic spectrum, typically the wavelengths of the visible range.
  • the Dewar device 1 and in particular the case 4 comprises the fixing device 7 carrying out a reversible fixing of the case 6 of the watch 3 on the inner peripheral wall 12 of this box 4.
  • This fixing device 7 which is also called “reversible fixing device” comprises at least two connecting members 9a visible on the figures 1 to 3 which are each connected to an attachment zone 13 of said box 6 from at least one telescopic bar 9b, 9c.
  • the fixing device 7 comprises two connecting members 9a and four telescopic strips 9b, 9c.
  • these two connecting members 9a are able to cooperate each with two telescopic bars 9b, 9c in order to ensure the fixing of the case 6 of the watch 3 in the enclosure 5 of the case 4 from attachment zones 13 of this box 4.
  • Each connecting member 9a is arranged on the inner peripheral wall 12 of the enclosure 5 of the box 4, being arranged facing the attachment zone 13 with which it is brought to cooperate within the framework of this fixation.
  • This arrangement of each connecting member 9a on the inner peripheral wall 12 can be achieved by clipping, interlocking, welding, gluing or even screwing.
  • each connecting member 9a comprises two contact zones 17 which are arranged in this member 9a opposite each other, each being arranged on a side wall of this member 9a.
  • the arrangement of each contact zone 17 on a side wall is made so that it is positioned opposite or even aligned with an opening included in the horn 16. As will be seen later, this opening is intended to be connected with this contact zone 17 via a telescopic bar 9b, 9c.
  • the contact zone 17 is capable of receiving a first end 18a of the bar 9b, 9c and the opening present in the horn 16 which is preferably blind, is itself configured to receive a second end 18b of said bar 9b, 9c.
  • each telescopic bar 9b, 9c comprises a body formed from first and second parts 14a, 14b which are interconnected in particular by an elastic member 15, for example a spring positioned in this second part 14b of this body of the strip 9b, 9c.
  • the first part 14a of this bar 9b, 9c which is able to slide in the second part 14b, comprises the first end 18a of the bar 9b, 9c which is capable of cooperating with the contact zone 17 of each connecting member 9a.

  • such a fixing device 7 contributes to arranging the case 6 of the watch 3 in this case 4 so that the crystal 11 of this case 6 of watch 3 is arranged opposite crystal 10a of case 4 so that the information included on the dial and/or the display interface of this watch 3 can be perceived through transparent crystal 10a of the box 4 by the user carrying the Dewar device 1.
  • such a Dewar device 1 provides the mechanical and/or functional components 2 of the watch 3 with very good thermal insulation with respect to the external environment by preventing heat loss from the watch case 6 by radiation.
  • the temperature outside the device 1 reaches extreme values, typically of the order of ⁇ 125 to +125° C.
  • the temperature inside the enclosure 5 remains substantially equal to the temperature present in case 6 of watch 3 during its arrangement in case 4, typically around 20°C.
  • the temperature present in the case 6 of the watch 3 is a temperature which does not hinder the correct operation of the watch.
  • This temperature is maintained over a period which is 5 to 18 times longer than the period during which such a watch case would be capable of preserving an operating temperature of its components 2 by being located directly in such an environment where such temperatures prevail. in particular extreme (that is to say by being located outside the case of the Dewar device). It is thus conceivable that such a configuration makes it possible to protect the mechanical and/or functional components 2 of the watch 3, as well as to participate in ensuring their operation in an optimal manner under extreme outside temperature conditions.
