This Cartier Tonneau XL reference 2435 is a rare pre CPCP example that highlights Cartier’s dedication to elegant case design and refined craftsmanship. The elongated tonneau case is crafted from platinum, giving the watch a subtle yet substantial presence on the wrist, and it is paired with an 18k white gold Cartier folding clasp. Powered by a hand wound movement, the watch retains the slim and curved profile that defines the Tonneau line, offering exceptional comfort and timeless sophistication. The silvered dial is beautifully preserved, showing the signature Cartier Roman numerals and blued steel hands in superb condition. Fitted with a new light blue Cartier strap, this Tonneau XL remains in very good overall condition with only minimal signs of wear. A striking and elegant piece from Cartier’s pre CPCP era, it perfectly captures the maison’s distinctive aesthetic and artisanal excellence.
