The Ingenieur Chronograph is powered by the IWC-manufactured 69375-calibre movement with a bidirectional pawl-winding system and a 46-hour power reserve. Used in combination with the tachymeter scale, it also shows the average speed achieved over a measured distance of 1,000 metres. The transparent sapphire-glass back provides a view of the 69375-calibre movement in all models. The stainless-steel model with a stainless-steel bracelet features a silver-plated dial and gold-plated hands.
