De façon avantageuse et particulière, au moins un des constituants métalliques de la boîte 100, et plus particulièrement l'ensemble des constituants métalliques de la boîte 100, à l'exception des glaces et joints d'étanchéité, est réalisé dans un matériau permettant d'obtenir une fréquence critique de rayonnement inférieure ou égale à celle obtenue avec une exécution en alliage d'or ou en or. Plus particulièrement, la carrure 10, la lunette 2, et le fond 5 quand la boîte 100 comporte un fond 5 métallique, sont réalisés dans le même alliage. Plus particulièrement encore, cet alliage est un alliage de titane, convenant bien aux contraintes mécaniques et aux contraintes d'étanchéité usuelles à au moins 5 bar, et dont le pouvoir rayonnant est supérieur à celui de l'or, ce choix permettant d'obtenir une fréquence propre dans la fourchette recherchée de 4 kHz à 6 kHz. Dans une variante particulière, cet alliage est du « titane grade 5 », comportant 90% de titane, 6% d'aluminium, et 4% de vanadium; dans une autre variante cet alliage est un alliage précieux de titane, et notamment de titane et d'or, selon l'une des demandes de brevet PCT/EP2015/080211 et PCT/EP2015/080270 au nom de Montres Breguet SA. Plus particulièrement on choisit un alliage titrable.Advantageously and particularly, at least one of the metallic constituents of the box 100, and more particularly all the metallic constituents of the box 100, with the exception of the windows and seals, is made of a material allowing obtain a critical frequency of radiation less than or equal to that obtained with a gold alloy or gold alloy. More particularly, the middle part 10, the bezel 2, and the bottom 5 when the box 100 has a metal base 5, are made of the same alloy. More particularly, this alloy is a titanium alloy, which is well suited to the usual mechanical stresses and sealing stresses of at least 5 bar, and whose radiating power is greater than that of gold, this choice making it possible to obtain a natural frequency in the desired range of 4 kHz to 6 kHz. In a particular variant, this alloy is "titanium grade 5", comprising 90% titanium, 6% aluminum, and 4% vanadium; in another variant, this alloy is a precious alloy of titanium, and in particular of titanium and gold, according to one of the patent applications PCT / EP2015 / 080211 and PCT / EP2015 / 080270 on behalf of Montres Breguet SA. More particularly, a titratable alloy is chosen.
