The lever pallets are made from monocrystalline black diamond and the escape-wheel from silicon. Easium™ carbon-nitride is used here for the first time, in order to eliminate any need for lubricating the escapement parts and to avoid wear of the shock-absorbers. The barrel grease is replaced by a graphite powder-based mixture that is stable at even extreme temperatures.
