Product Description Inspired by the pistons of a car Sinn, the Mechanique Veloci made its debut in 2006 with the Quattro Valvole, which housed four automatic movements in one case. In 2011, the watchmaking base was moved from Italy to Switzerland, further evolving the Quattro Valvore and succeeding in running four watches independently in one self-winding movement. This [Quattro Valvolenardi] is an interesting model that uses mahogany wood as the case material for the sturdy and lightweight titanium and middle case. It is a rare model of 50 limited to the world.
