The “Coeur Vitré” version of the Chrono 4 Bellissimo, available only to order, is made in steel or 18 ct pink gold. An exclusive model with a precious “heart”: its refined movement, finely hand crafted with spiral motifs, can be seen through the sapphire crystal caseback, as well as the special oscillating weight, a little jewel in 21 ct white or pink gold, worked in dexterous detail, adopting the stylised motif of the four counters.
