Parmigiani Fleurier has revisited the aesthetics of the first watch designed by its founder, introducing a new dial. The slate-coloured dial features a captivating guilloché decoration that evokes the spiral structure of a pine cone – one of the innumerable examples of the Golden Ratio found in the natural world.
"The decoration is so captivating because it is based on the Golden Ratio. Within it, you see Fibonacci's spirals, reproducing a harmony that is everywhere in nature. ". This is how Michel Parmigiani describes the hand-guilloché dial of the new Toric Chronomètre. Its concentric pattern evokes the arrangement of the scales on a pine cone.
Hand guilloché is an artisanal technique, of which few manufactures have such a fine mastery, in which the material is engraved to produce a repeating decorative pattern.
The Toric's aesthetic impact and unique character come from its bezel, which features a hand-knurled design. Since the Toric was created in 1997, each piece has passed through the expert hands of the same craftsman in Le Noirmont (Jura), who has produced every one of the Toric bezels. Knurling is a rare and distinctive art; it consists of manipulating the material with a wheel that leaves the imprint of its notches in the metal.
The Toric Chronomètre Slate is powered by the COSC-certified PF441 proprietary calibre. The movement meets exacting standards in terms of accuracy. The word "Chronometer", from the Greek "time measurement", provides a fitting name for the piece.
