It is constructed in the purest of chronometer traditions with a extra-flat 4 mm thick movement with 18k gold plates and bridges. There are two barrels of homogenous movement delivering a linear force to the escapement for over 56 hours. The escapement beats at a frequency of 21,600 vibrations per hour.
