The Harmony collection is all about modern luxury, with new movements and unique features to fit a busy lifestyle. The dual time function is a popular and practical complication for both men and women. Vacheron Constantin has designed the self-winding Caliber 2460DT specifically for this must-have feature. The latest models have anthracite function hands and come in white or pink gold. This version features an 18k 5N pink gold case and a brown alligator strap.
