The case of the Pilot?s Watch Chrono-Automatic is bigger and now measures 42 instead of 39 mm. Optically, it has a considerably more striking presence than its predecessor. The dial has been modified to match the design of the Big Pilot?s Watch, as can be seen, among other things, from the eye-catching chapter ring and the propeller-like hands. The robust 79320 calibre chronograph movement functions as a stopwatch with aggregate timing up to 12 hours and shows the day and the date. The automatic chronograph comes with a matt black crocodile leather strap with a stainless steel buckle. Alternatively, it is available with a stainless steel bracelet, equipped with a folding clasp and the special IWC bracelet system that allows it be adjusted quickly and simply to the size of the wearer?s wrist.
