The IWC Mark XII was sold and produced from mid-90s to late 90s until it was replaced by IWC Mark XV in 1998-1999. Ever since then, pilot watches have represented a major part of IWC catalogue in various forms. Among normies, IWC is probably best known known for their pilot watches. After the introduction of the Mark XII, IWC introduced many other iconic pilot’s watches such as the Big Pilot and Pilot’s Chronograph. The Mark series continues still today as an entry-level watch in the IWC collection.
