Is your Mark XVIII
the real deal?
The IWC Mark XVIII continues the Pilot's Watch lineage with clean, functional design. As an accessible entry to IWC, it's frequently counterfeited. Here's how to verify authenticity.
How to authenticate a Mark XVIII
Matte Black Dial
Distinctive matte finish with anti-reflective properties. Genuine dials are perfectly flat without gloss or sheen. Dial should have uniform matte surface. Counterfeits have shiny or uneven surfaces.
Pencil Hands
Simple pencil-style hands with luminous coating. Hands should be perfectly straight and uniform width. Lume should be evenly applied. Counterfeits have bent or unevenly lumed hands.
Caliber 35111 Movement
Based on Sellita SW300-1 with IWC modifications. Movement should show IWC engraving and proper perlage decoration. Rotor has IWC branding. Counterfeits use unmodified movements.
Soft Iron Inner Case
Antimagnetic protection via soft iron inner cage (not visible). Case back should indicate antimagnetic properties. This protects against magnetic fields. Counterfeits omit this feature.
Date Window at 3
Simple date window with white background and black numerals. Date should be perfectly centered in window. Font should match IWC style. Counterfeits have off-center or magnified dates.
Case Proportions
Clean 40mm case with proper lug proportions and brushed finishing. Crown should be signed with IWC logo. Case should feel substantial. Counterfeits have incorrect proportions or unsigned crowns.
Mark XVIII counterfeit warning signs
Shiny or Glossy Dial
The dial should be perfectly matte without gloss. If the dial reflects light or has a shiny surface, it's counterfeit.
Bent or Uneven Hands
Pencil hands should be perfectly straight with uniform width and even lume application. Bent hands or uneven lume indicate poor quality or counterfeit.
Generic Movement
If the movement lacks IWC branding, has incorrect decoration, or shows a different base caliber, it's counterfeit.
Unsigned Crown
The crown should have the IWC logo clearly engraved. Missing or poorly stamped logos indicate a counterfeit.
