Parmigiani Fleurier

Tonda PF Skeleton Steel


Based upon the foundational Tonda PF Micro-Rotor, the Tonda PF Skeleton displays the skill and craftsmanship of the artisans at Parmigani Fleurier. This unique novelty skips the dial altogether to reveal the open-worked caliber PF777. Skeletonized and beveled to perfection, the movement bridges and plates have been galvanized with a NAC coating. This NAC alloy is from the platinum family of metals and contains rhodium and osmium. This treatment is responsible for the dark grey color of the main plate.

The Design
The monochromatic look of the Tonda PF Skeleton and its movement is accentuated by the lack of traditional jewel bearings, typically made of rubies. Instead, Parmigiani Fleurier watchmakers utilized zirconium jewels to achieve this colorless look so as not to distract from the beauty of the movement.

Looking at the indicators, we are treated to the familiar Delta-shaped hands in solid gold consistent through the Tonda PF line. Slim and long, they're almost entirely open-worked. The bezel, which is crafted out of solid platinum, is a reference to the early Toric models with a polished element and an outer surface that is knurled by hand. Rather than using the same steel as the rest of the case and bracelet, Parmigiani Fleurier has elected to work with this highly precious metal, not for exclusivity's sake but because it provides a better, shinier play with light and a more artisanal feeling once polished by hand.

The Movement
Unusual concerning this offering is its self-winding feature, where most skeletonized watches are wound by hand; the PF777 is equipped with a full-sized open-worked rotor mass in 22k rose gold. This oscillating weight includes a floating "PF" logo set in sapphire at its center. This rotor winds bi-directionally, allowing for 60 hours of running autonomy. The PF777 has been equipped with INCABLOC shock absorption technology, which protects it from less-than-optimal use.

Warranty & Authenticity:
The watch comes with the Greenwich Time 24 Month Warranty alongside a lifetime guarantee of authenticity.

The Parmigiani Fleurier brand - a watch-making adventure that transcends the mundane - was created in Fleurier in 1996 and was guided by the passion of a man who remained faithful to the very essence of the watchmaker. Michel Parmigiani, master horologist, renowned restorer, and talented creator of mechanical time-keepers, dedicates his knowledge, which has been enriched by past and present teachings, to the benefit of the brand.

The Sandoz Family Foundation, who had tasked a young Michel Parmigiani to lead the restoration of their horological artifact collection, became interested in bringing Parmigiani's masterful work to the consumer market. In 1996, with the backing of the Sandoz Foundation, Parmigiani Fleurier was able to fit out its manufacturing workshops with the means to produce exceptionally high-quality goods. In less than 10 years, it achieved near complete vertical integration, and the industrial equipment deployed constitutes one of the rarest and most complete manufacturing workshops in Switzerland. The very essence of haute horology, such as attention to detail or the beauty of the embellishment of a simple or highly complicated movement, is the subject of great attention at Parmigiani Fleurier and is the reason for its international recognition.

Thoughts on the Tonda PF Skeleton:

"One of the most impressive elements of the Tonda PF Skeleton is its proportions. At 8.5 mm thin, and 40mm in diameter, the dimensions of the watch, paired with the depth of the skeletonized dial, create a dynamic visual presence that furthers its understated elegance."
