Cartier's 'Ballon Bleu de Cartier' watch gets its name from the cabochon nestled at the side that resembles a floating balloon and is encrusted with 50 brilliant-cut diamonds totaling 0.63-carats. This 33mm timepiece has been flawlessly assembled with polished stainless steel links that adjust at the back for a comfortable feel. The curved case has a silvered guilloché opaline dial and black Roman numerals centered with blued steel sword-shaped hands. It's the perfect gift to pass down for generations to come.
