Arnold & Son, Constant Force Tourbillon

Arnold & Son pushes precision chronometry ever further with the Constant Force Tourbillon, featuring a patented constant force device with 60-second tourbillon and true beat seconds.

 

The symmetrical movement architecture of the Constant Force Tourbillon movement pays tribute to Arnold & Sons' historic marine chronometers. At the top, two visible mainspring barrels and the constant force device provide optimal power to the tourbillon at the bottom of the dial.
