Breguet Tradition Répétition Minutes Tourbillon 7087 Replica Watch is shaped for the resonant frequencies of the desired sounds. Contrary to the 7800 model that featured a metallic glass membrane, this one is made of gold and affixed to a sapphire crystal providing a stunning view of the movement.Like the Classique La Musicale 7800 model, this new Tradition 7087 features an acoustic chamber built into the case – technically termed a Heimholz cavity – whose role is to increase the sound level of the minute repeater while filtering the sounds from the mechanism. This chamber can be glimpsed through eight small holes arrayed on the lower bezel encircling the caseback. In this model the cavity is rectangular in profile and encircles the movement, from which it is separated by a membrane designed to seal the movement from the outside air.
Unlike the magnetic governor of La breguet tradition replica which remains hidden from sight, the decorated and open-worked version on the Tradition Répétition Minutes Tourbillon is placed in full view on the dial side of the watch. It has also been the subject of much calculation and optimisation to adapt it to the minute repeater mechanism. Since the mechanical elements do not touch each other, this exclusive Breguet governor is perfectly silent.These impressive innovations are complemented by the use of a magnetic strike governor, developed on the basis of a concept featured in the Classique La Musicale model. The faster the rotation, the greater the resistance; and conversely, the slower the rotation, the weaker the resistance. This patented system is composed of silver weights surrounded by magnets placed around the circumference of the strike governor. The result is a device that ensures constant rotation speed, since both acceleration and braking meet with counter-resistance of identical intensity. The use of a magnetic governor brings an added advantage: silence. As they turn within this magnetic environment, the weights produce an electric current that runs counter to the magnetic field of the magnets. The titanium used to make the bridges and the mainplate of the Tradition, along with appropriate sizing of the components, serves to avoid propagating the noises from the striking mechanism, by filtering their transmission through to the exterior.
The striking mechanism is activated by pressing a bayonet pusher instead of by pulling the customary dedicated slide. The energy required is delivered via a chain – a transmission mode reminiscent of the famous No.Above and beyond these exceptional technical characteristics, the breguet replica watch is also a tribute to Breguet’s long history. It is thus naturally equipped with a tourbillon, along with an automatic winding peripheral rotor system.
