An enduring and elegant choice, this pioneering French brand has been at the cutting-edge of watch design since the early part of the last century. The allure of a Cartier watch has seen them adorn the wrists of royalty throughout the generations. This refined and understated Cartier Ballon Bleu watch in stainless steel, regularly seen on Kate Middleton, features the now iconic 36.6mm case, with a cabochon sapphire-set crown protected by the curve of the case. The white guilloché dial is an elegant backdrop for the blued-steel hour and minute hands and oversized black Roman numerals, powered by the Cartier calibre 690 quartz movement. Graceful and timeless, the Cartier Ballon Bleu watch is a true classic that can slip seamlessly from day to night.
