The backing is also made of transparent PMMA, and it is joined to the casing using a tension ring which ensures a perfect seal.
Both the support for the gearing and the dial are integrally formed of transparent PMMA, although in this case we have decided to introduce different color variations at the heart of the watch.
These parts require manipulation and control of the highest precision, only available to highly sophisticated industrial equipment. Therefore it will be produced in Switzerland, where competence in matters of precision and miniaturization, as well as the art of watchmaking, are indisputable and offer total quality assurance.
