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. This timepiece has a case made from 18-carat 5N gold, a slate-coloured dial, gold-plated hands and a black alligator leather strap.
