Mark XVIII Le Petit Prince

The IWC Mark XVIII Le Petit Prince is a special edition within IWC’s acclaimed pilot’s watch lineage, distinguished by its deep blue sunburst dial inspired by Antoine de Saint-Exupéry’s beloved novella. This model carries forward the legacy of the classic Mark series—originally designed for aviators—while adding a literary and visual twist that appeals to both collectors and fans of the story. The Le Petit Prince editions are produced in limited runs, giving them a unique place in the Mark XVIII lineup and often making them more sought-after than standard black-dial variants.

Key reference for this model is IW327010, featuring a 40mm stainless steel case, automatic Calibre 35111 movement, and a practical 60-meter water resistance. Compared to the standard Mark XVIII, the Le Petit Prince version is defined by its blue dial and a caseback engraved with the Little Prince—a detail that adds collector appeal. Variations in price are usually driven by condition, completeness (box and papers), and whether the original blue textile or brown leather strap is included, as factory straps are a valued part of the package.

When assessing examples, prioritize crisp dial color and caseback engraving, as fading or heavy wear can affect desirability. The IW327010 stands out for its slim profile and reliable movement, making it an easy daily wearer as well as a collectible. Early production runs tend to command a premium, especially if paired with full accessories and minimal signs of use.
