2. Vacheron Constantin Traditionnelle Tourbillon Retrograde Date Openface
This year, Vacheron Constantin spotlights the retrograde display. Three of its new releases feature a retrograde date, where the date indicator travels along an arc and jumps back to the start of the scale at the end of each month. The most avant-garde of the trio is the Traditionnelle Tourbillon Retrograde Date Openface, which combines a retrograde date with a tourbillon and an open dial. The open dial of this self-winding, pink-gold timepiece lets the brand showcase various finishings — including hand-guilloche on the upper part of the dial and a grey NAC surface finishing on the 2162 R31 movement.
