Already the creator of the thinnest automatic movement on the market, Manufacture Piaget continues its string of ultra-thin achievements by introducing a double record representing the culmination of three years of R&D. Presented at the SIHH 2013, the Emperador Automatic Minute Repeater houses the 407 parts of its entirely in-house developed 4.8 mm thick calibre within a 9.4 mm thick case comprising 69 parts. Such impressive mastery of miniaturisation is notably reflected in the thinnest movement part, measuring a mere 0.07 mm. The splendid stage-setting for the openworked and splendidly finished movement takes on a whole new dimension when it sounds its tune in the fifth octave. Its fabulous acoustics enable the hours to chime in G sharp and the minutes in A sharp. In order to preserve the purity of the sound throughout its duration, the calibre is equipped with an inertia flywheel regulating the rhythm between the beginning and the end of the striking sequence, thus ensuring an intense and regular tune.
