The IWC Schaffhausen Big Pilot Heritage 55 takes a 26 mm strap: measure between the lugs and that is the only number you need. A field or pilot watch at heart, it suits canvas, nylon and matte leather more than polished calf. With a 55 mm case and 60 m of water resistance, a thicker strap balances the case. Most straps here come with quick-release spring bars, so the swap takes a minute and no tool.
