The balance runs at 18,000 vph – the classic pocket watch frequency – and the tourbillon
link rotates once per minute. The seconds hand is carried on the tourbillon pivot, as well (as is customary with one minute tourbillons). The minute hand is 35mm long – so long, that in order to reduce weight, the hands were made, made
link not of gold (which is what it looks like) but rather, a light
link alloy of copper, nickel, and tin called Pfinodal.
