The Patrimony Ultra Thin Calibre 1731 is a minute repeating wristwatch launched at SIHH 2013. With the development, particular care was devoted to the acoustics of the Patrimony Contemporaine Ultra-Thin Calibre 1731, since its sound is the very reason for being of a striking watch. Various technical choices were made to ensure a crystal-clear and entirely tuneful tone. The gongs are not only connected to the case middle to as to amplify the sound, but also for the first time stacked rather than placed side by side. The case is made to be as one with the movement, within a clever composition incorporating such subtle parameters as the airflow between the mechanism and the case, designed to achieve optimal propagation of the sound. The quest for perfection does not end there, since the case itself has been built without joints so that the elements can interact literally metal against metal and thus enhance the amplitude of the sound, while the flying governor ensures a steady rate of the...
