Cartier Ballon Bleu de Cartier 40mm, 18k Rose Gold Leather WGBB0050 Watch

At the heart of this timepiece is the Calibre 1847 MC, a sophisticated mechanical automatic winding movement. This intricate mechanism, driven by the wearer’s motion, provides a reliable power reserve of approximately 40 hours. The captivating dark gray sunray-brushed dial, with its signature Roman numerals, is thoughtfully enhanced with a practical date aperture at the 3 o’clock position. The blued-steel sword-shaped hands provide a clear and elegant display. The watch’s most distinctive feature is the fluted crown, set with a blue sapphire cabochon and gracefully recessed into the case. With a case thickness of 12.45 mm, this beautiful timepiece is water-resistant up to 30 meters, perfectly blending technical excellence with a timeless design.
