Nothing short of a revelation, this marvelous watch transcends time and convention. A potentially unique prototype of the Cartier Panthère from 1917, it marks the very beginning of one of the most iconic design languages in horological history. Crafted in platinum and adorned with diamonds and onyx, this extraordinary piece is not just an exquisite creation from the early 20th century, but the earliest known expression of the Panthère motif in a wristwatch —a pioneering masterpiece that laid the foundation for one of Cartier’s most celebrated and enduring collections.
To hold this watch is to witness the precise moment when Cartier’s audacious spirit birthed an icon. The interplay of diamonds and sculpted onyx, evoking the sinuous elegance of the panther, was a revolutionary artistic concept —a design language that would define the Maison for over a century. Basically, this is where it all began. The platinum case, adorned with diamonds and onyx, is a celebration of geometric precision, embodying the bold, avant-garde aesthetics of the era. The dial, featuring timeless Roman numerals and blued-steel hands, is unmistakably Cartier. This watch is a wearable work of art, an artifact of glamour and creativity, transporting us to the golden age of design.
Given its pioneering history, this piece represents a truly coveted treasure for discerning collectors who appreciate the historical and museum-like significance, along with the enduring beauty of Cartier's creations. The "Breveté S.G.D.G." inscription on vintage Cartier dials indicates "Breveté Sans Garantie Du Gouvernement," a French patent marking signifying that the design was legally registered without state endorsement. Commonly found on early 20th-century Cartier timepieces, it underscores the brand’s pioneering innovations in horology. Almost impossible to find, it embodies Cartier’s pioneering spirit in merging high jewelry with haute horlogerie, laying the groundwork for the iconic Panthère watches that would follow.
