The piece has been worn and enjoyed by its one and only keeper and presents in good condition as can be seen in the images, with some wear related marks present on the case and bracelet. The Ballon Bleu was serviced by Cartier, Bond Street in 2016 and has recently enjoyed an inspection at Cartier with gasket and battery replacement. This reference was discontinued in early 2023, with the final retail price at £36,400, meaning that this lovely example that is complete with its original box and certification would complement the finest of collections and represents real value.
