A masterpiece of openwork design and aviation spirit, the Cartier Santos-Dumont WHSA0043 brings together heritage and modern watchmaking. With its large yellow gold case and skeletonised bridges shaped as Roman numerals, this timepiece reveals its heart while retaining clarity and elegance. Topped with a platinum micro-rotor in the shape of Santos-Dumont’s Demoiselle biplane, it blends storytelling with function. Two interchangeable alligator straps and a slim profile make it versatile enough for both bold presence and refined wear.
