Natural harmony

A contemporary watch that draws on ancient design principles, the Parmigiani Fleurier Toric Chronometre Guilloché Dial features a mesmerising concentric pattern based on Fibonacci’s Spirals, a.k.a the Golden Ratio.

This is a mathematical ratio where one part (a) divided by a smaller part (b) equals (a)+(b)÷(a). Frequently seen in nature, from the most powerful tornadoes to the tiniest shells, it’s intrinsically pleasing to the human eye (and yes, even our own faces show this ratio… it really is a magic number). In Parmigiani’s case, its concentric pattern is expressed using the artisanal technique of hand guilloché. At 12 o’clock and 6 o’clock respectively, the elliptical Parmigiani Fleurier logo and the word “Chronomètre” used by COSC (Swiss Chronometer Testing Institute) stand out from the dial’s decoration.

The javelin-shaped hands are semi-openworked to complement the subtle minute track around the circumference and the Arabic numerals.

“The decoration is 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 Toric Chronomètre.

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. Each knurling design is unique, just like each Toric. The red gold case houses the COSC-certified PF441 proprietary calibre.
