The Ingenieur Chronograph is powered by the IWC 69375-manufactured caliber, with a bidirectional ratchet refill system and a 46-hour driving range. With the help of the tachymeter scale it is also possible to measure speed on a path of 1000 meters. The sapphire crystal caseback, available in all versions, allows you to observe the 69375 caliber. The timepiece is made of 18-carat red gold with a slate-colored dial, golden hands and black alligator leather strap.
