The fourth episode in Harry Winston’s tourbillon story involves a tri-axial tourbillon in which the tourbillon itself is housed inside three concentric cages, each of which revolves around a different axis and at a different speed—more than enough to confound gravity. The limited edition of 20 pieces comes in a 47mm polished white-gold case with DLC-treated Zalium® on the caseband. The tourbillon takes pride of place beneath a separate domed sapphire crystal, relegating the separate hour display to 2 o’clock and minutes to 9 o’clock.
