The manual-wind movement contains 420 components and features two barrels to power the timekeeping and striking functions separately. The 18k yellow gold case typically measures 39mm and houses a white lacquer or enamel dial with Roman numerals and a blued steel handset. Only eight examples of this complication were produced in total across all metals, making it one of the rarest modern timepieces.
