Inversion Principle Red Gold is a limited edition of 10 pieces in red gold.
While Inversion Principle is first and foremost a very exclusive haute horlogerie timepiece, subtle elements and mechanisms discreetly feature key attributes of the AK47. Each timepiece incorporates a plate on the back made from the transformed steel of a destroyed assault weapon.
Inversion Principle: Orbiting on high above the movement, the central 3-minute flying tourbillon dominates the three-dimensional dial and mesmerizes the eye. Three second-hands, equally spaced 120° apart around the tourbillon cage, arc sedately across the seconds-scale above the tourbillon and ‘Fonderie 47’: ‘Sedately’ because tourbillon revolves at just 1/3 of the speed of a traditional one-minute tourbillon.
While only one second-hand is visible at any time − the other two are hidden under the gold rifle-sight inspired frame set into the sapphire crystal − their positions are revealed by blued screws joining the outer tourbillon cage and inner three-arm hub.
The long 6-day power reserve has both a lateral indication via a sapphire window set into the left side of the case band and a second indication visible through the display back. The display back reveals the stunning sunray guilloche pattern radiating out from the ratchet wheel, which is capped by a dark plate of transformed steel from a destroyed AK47.
The plate is in the form of the Fonderie 47 brand symbol and rotates as the watch is wound. ’56-3701F42′, the serial number of the destroyed weapon the metal is from, is elegantly hand engraved beside the plate.
With a three-minute central flying tourbillon, instantaneous jumping hours and retrograde minutes that snap into place in sharp, precise actions similar to gun mechanisms, and a lateral power reserve indication providing a discreet visual link to the ejection port of an AK47, Candaux delivered all that and more.
“Fonderie 47 has allowed us to create a unique timepiece, not simply for the purpose of creating a luxury watch, but for a noble purpose.” David Candaux (watchmaker)
