Early on during its establishment in 1847 by Louis Francois Cartier, the brand had the Royalties seal of approval. Countless precious ornaments and sensational timepieces later, it came to represent haute joaillerie and horlogerie, and represented it well. The Cartier Rotonde collection is a perfect example of the firms excellent command of complications. Sporting a chronograph, astrotourbillon, jumping hours, perpetual calendar, 8-day power reserve, or minute repeater, the Cartier Rotonde proves it is more than just a variety of stunning faces. But it certainly doesnt disappoint in that area. Crafted from 18k gold, platinum, or titanium, it features a circular-grained crown with a sapphire cabochon, Cartier Roman numerals, and blued steel hands. Measuring 35mm to 47mm, the mechanical Cartier Rotonde definitely sets the standard for top-notch watchmaking.
