DOUBLE ROTATION
This elaborate, one-of-a-kind fine watchmaking piece saw the light of day in the manufacture’s workshops thanks to an original concept proposed by an apprentice watchmaker, Loris Spitzer.
A two-toned globe, offset towards 9 o’clock, on the varnished Obsidian dial of IWC‘s Portugieser Hand-Wound Tourbillon Day & Night, completes its revolutions in 24 hours on its own axis, totally in tune with the rotations of the golden hour and minute hands. At the same time, a flying tourbillon twirls in one minute at 6 o’clock. Even though this device, imagined to limit the effects of the Earth’s gravity, flaunts some 56 components, it only weighs 0.675 grams. To optimize its running, its parts are topped with Diamond Shell® technology. This silicon-diamond coating significantly reduces friction while improving energy transmission to the inner workings of caliber 81925. As such, this hand-wound movement delivers a comfortable power reserve of 84 hours. The existence of a sapphire-crystal caseback invites to admire its baseplate decorated with circular Côtes de Genève designs. The regulating device and the stylized portrayal of Earth are also unveiled in their entirety.
This mechanical architecture reigns inside a 42.4 mm-diameter, 750/1000 Armor Gold® case. This alloy, comprising 75% pure gold stands out from red gold through its greater hardness and resistance to wear and tear. Its warm hues, emphasized by its polished and brushed finishes, marry harmoniously with the dark black scenography. The black alligator strap fashioned in the workshops of well-known Italian footwear creator Santoni adds to this watch’s delicate, unparalleled spirit.
