BLANCPAIN – L-evolution Tourbillon Carrousel

The tourbillion, invented by Abraham-Louis Breguet in 1801, is a mechanical system which houses escapement fittings and the regulator in a rotating cage. As well as turning on itself alongside the lever, balance wheel and spring, it also spins around the seconds wheel. The carrousel, designed by Danish watchmaker Bahne Bonniksen in 1892, is a similar system but it has two wheel trains: one to tilt the cage and the other to supply energy to the balance wheel and escapement. These two watchmaking masterpieces counter the effect of gravity on the watch’s function. This L-evolution by Blancpain brings both devices together in a single movement. Two cylinders wound by a single crown supply energy to both regulators. This extraordinary movement with NAC-coated peen patterned bridges is housed in a 47.4mm platinum case. Price: 348,000 CHF
