Short answer
IW327010 is the IWC reference for the Pilot's Watch Mark XVIII "Le Petit Prince." A replica of it is a copy of that 40 mm steel watch with a blue dial. Quality varies by seller and by price. Three checks decide most of the outcome: case size, dial print, and movement.
Genuine specs to compare against
- Case: steel, 40 mm diameter, about 11 mm thick
- Dial: blue, white numerals and hands, date at 3 o'clock
- Movement: calibre 35111, automatic, 42-hour power reserve
- Crystal: sapphire, flat, antireflective coating on both faces
- Water resistance: 6 bar (60 m)
- Lug width: 20 mm
- Strap: brown calfskin
Measure the replica against these numbers. A case that reads 42 mm wide or 13 mm thick is a different watch with a Mark XVIII dial. Sellers post case diameters that are rounded or copied from the listing above them. Ask for a caliper photo.
Case and dial checks
- Date window: on the genuine watch it sits near the inner edge of the minute track, and the frame is thin.
- Numerals: edges should be clean under 10x magnification. Soft or filled edges mark a low tier dial.
- Crown: rounded profile, IWC lettering engraved into the metal, not printed on top.
- Caseback: engraving depth. Shallow laser etching is the fault seen on entry level copies.
- Hands: flat, matte finish. Glossy hands with rounded edges are wrong for this reference.
Movements used in replicas
Most copies of this reference run one of three movements: a Chinese automatic built on a Miyota 9015 pattern, a Seagull ST2130, or a decorated copy shaped to look like the 35111. The first two beat at 28,800 vph. The genuine 35111 also beats at 28,800 vph with a 42-hour reserve, so beat rate alone does not prove anything. Ask the seller to name the movement. A seller who cannot name it is a risk.
Price tiers
Entry copies sell for about $70 to $150. Mid tier runs $200 to $350. Top tier runs $400 to $700. The step from entry to mid tier buys a better dial and smoother winding. The step from mid to top tier buys a closer case profile and better caseback finishing. Above $700, the gap to a used genuine Mark XVIII narrows and the copy stops making sense on cost.
Questions to send a seller

Legal note for US buyers
Replica watches carry trademarks owned by IWC Schaffhausen. Import into the US can lead to seizure by Customs and Border Protection, and sale can lead to claims from the brand owner. The buyer carries that risk. This guide does not change it.
