The IWC Schaffhausen Ingenieur Automatic 40 Stainless Steel / Silver takes a 14 mm strap: measure between the lugs and that is the only number you need. With a 40 mm case and 120 m of water resistance, a strap of medium thickness keeps the balance. Automatic movement. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
We do not sell watches. This page exists to find the straps that fit this one.
