Inversion Principle is a completely original timepiece, designed by Adrian Glessing and developed and produced by David Candaux/Du Val Des Bois exclusively for Fonderie 47.
The sale of each timepiece will fund the destruction of one thousand assault rifles in Africa, creating a safer environment for aid and development. This is a strategy that Fonderie 47 founder Peter Thum already implemented successfully in creating Ethos Water to fund clean water projects in Africa and around the world.
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 had to reflect the finest Swiss watchmaking traditions; our principles and our mission; and be truly innovative all at the same time. That was no easy task, but thanks to a great team, I think we well and truly achieved that aim.” – Peter Thum (Fonderie 47 founder)
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.
“I feel one of the biggest achievements of this timepiece is the very logical way you read the time.” – Adrian Glessing (Inversion Principle designer)
A first, or even a second, glance is unlikely to divulge any obvious similarity between jumping hours, retrograde seconds and an AK47; however, avoiding blatantly obvious connections is the aim. On a more ethereal level however, gun mechanisms snap sharply and precisely into place: as does the instantaneous jumping hour at 12 o’clock as it changes the hour; and the large 240° retrograde seconds hand as it flies back to zero each hour across the bottom of the dial. Each press of the quick-set pusher in the crown advances the jumping hours by one hour.
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. The serial number of the destroyed weapon, ’56‑3701F42,’ is elegantly hand engraved beside the plate.
“A mentor taught me what he thought generated the fundamental values of watchmaking: The eye; the hand; and the heart. These are values that guide my work. A timepiece built around these values generates powerful emotions.” – David Candaux (Inversion Principle watchmaker)
