Pre-owned IWC Pilot’s Watch Mark XVIII ref. IW327001. Introduced in 2016, the Mark XVIII returned the collection to a cleaner, more traditional layout by replacing the Mark XVII’s oversized date display with a classic single-date window. IWC also reduced the case diameter from 41mm to a more wearable 40mm, bringing the watch closer in spirit to the legendary Mark XI military pilot’s watch that inspired the series. As with every great pilot’s watch, legibility takes center stage. This example features a matte black dial with crisp white Arabic numerals and high-contrast hands that make reading the time effortless at a glance. The stainless steel case houses a soft-iron inner case to help shield the movement from magnetic fields, while the self-winding caliber 30110 provides a reliable 42-hour power reserve. Completing the watch is a premium black calfskin strap by Santoni, giving the ref. IW327001 a refined finish that wears just as comfortably in everyday settings as it does in the cockpit.
