This grand complication was created explicitly for connoisseurs of striking watches. It stands out with its open architecture that allows the minute repeater mechanism including the hammers and gongs to be admired in action while the watch is being worn on the wrist. The aesthetic appeal of the manually wound caliber R TO 27 PS was subtly reworked to highlight its full beauty. The rose-gold case features white-gold intarsias engraved with foliage motifs.
