Patek Philippe R 27 Q

The R 27 Q is a micro-rotor automatic movement manufactured by Patek Philippe. It combines a perpetual calendar with a minute repeater complication featuring two cathedral gongs, activated by a slide in the case band. The 467-part movement beats at 21,600 vph and contains 29 jewels, bearing the Geneva Seal hallmark. This caliber powers several of the manufacturer's grand complication wristwatches.
