Vacheron Constantin revealed how his Caliber 2460 QCL / 2 works on New Traditionnelle calendar clocks.
The days of the week and months of the year are displayed on clear disks that appear behind the shiny sapphire until they reach the small white back stones that illuminate the sound.
The days of the month are shown in the path that is above the singing distance, and are pointed by the middle hand.
The lunar phase disc at 6 a.m. contains two real Earth images that appear from the back of a clear sapphire sapphire.
There are two types of 41mm, one in 18ct white gold, the other in pink gold.
Navigation 2460 QCL / 2, with its Malta Cross-carrying gold rotor, is displayed on the ground and from the singing side.
