Quick answer
A replica IWC Pilot's Watch Mark XVIII copies a 40 mm steel case, an 11 mm thickness, a 20 mm lug width, and a black dial with a date at 3 o'clock. Good copies run a 28,800 vph automatic movement behind sapphire glass. They are not magnetic shielded. Price for a decent copy sits between USD 250 and USD 500. The genuine watch starts near USD 5,000 new.
What the Mark XVIII is
IWC released the Mark XVIII in 2016. It replaced the Mark XVII and brought the line back to a 40 mm case. References include IW327001 with a black dial and leather strap, IW327002 on a bracelet, IW327010 with a blue dial, and IW327006 in titanium. The layout traces to the Mark 11 from 1948: triangle at 12, large Arabic numerals, baton hands, no sub-seconds.

What changes on a replica
Case
Most copies use 316L stainless steel. Hardness and finish differ from the genuine case. Some copies measure 40.5 mm to 41 mm at the bezel.
Movement
Common options are the Miyota 9015, the Seagull ST2130, and the ETA 2892 or Sellita SW300 sold as upgrades. All run at 28,800 vph. Accuracy varies by unit. No maker publishes a per-batch tolerance.
Magnetic protection
The genuine Mark XVIII has a soft-iron inner case. Copies do not. A copy will drift in a strong magnetic field.
Water resistance
Listing pages claim 50 m to 100 m. Gaskets on copies get no factory pressure test. Do not swim with one.
Dial and lume
Date font, lume color, and hand length are the three tells. Genuine lume is Super-LumiNova. Copy lume fades in 20 to 40 minutes.
Checks before you buy
- Ask for the movement name, not the word Swiss.
- Ask for a photo of the caseback engraving.
- Check the date window for a beveled edge and center alignment.
- Check the crown for the IWC fish logo.
- Check lug holes. A 20 mm spring bar should sit flush.
- Ask for a timegrapher print. A rate inside plus or minus 10 seconds per day marks a good copy.
Price bands
Entry copies cost USD 80 to USD 150. These use a Miyota or DG2813 movement, mineral glass, and a printed dial. Mid copies cost USD 250 to USD 400 and add sapphire glass, a 9015 or ST2130 movement, and applied markers. Top copies cost USD 450 to USD 700 and add closer case shaping, AR coating, and an ETA or Sellita movement. A used genuine Mark XVIII runs USD 3,000 to USD 4,500. A new one runs about USD 5,000 to USD 5,600.
What is not known
No maker publishes batch specs for replica Mark XVIII watches. Case alloy, gasket material, and lume grade change between runs. Photos from one seller do not describe the next batch.
