If you are shopping for a fake IW327010, the reference number for the IWC Pilot's Watch Mark XVIII Le Petit Prince, treat it as a replica from the first click. Buy only from a seller who states in writing that the watch is a copy, sends dated photos and a short video of the exact unit you will receive, accepts a payment method with buyer protection, and offers a return window. Walk away from any listing that hints at genuine parts, claims original Swiss manufacture, or refuses refunds. Assume the watch can be seized in transit and that IWC will not service it.
The real IW327010, in short
Knowing the original is the only way to judge a copy. The genuine Mark XVIII Le Petit Prince is a 40 mm stainless steel automatic with a sunburst blue dial, printed white numerals, a date window at 3 o'clock, and a solid case back engraved with the Le Petit Prince artwork. Inside is caliber 35111, a Sellita SW300-1 base running at 28,800 vibrations per hour with about 42 hours of power reserve. The crystal is sapphire with anti-reflective coating on both faces, water resistance is rated around 6 bar, and the lug width is 20 mm.
What to look for in a first copy
Dial and hands
The sunburst finish is the hardest detail to copy. In direct light the blue should shift from near black at an angle to a mid blue head on, without a flat, purple, or metallic cast. Numerals should be crisp and evenly spaced, and the date window should be cleanly cut with the date centered rather than sitting high or low. Hands should match the original shape, and the lume should sit level inside the markers instead of spilling over the edges.
Case, crown and case back
Ask for caliper photos of the diameter, thickness, and lug width before you pay. The case should show brushed top surfaces with polished bevels and sharp transitions. The crown should be signed, sit flush, and screw down without grit. The case back engraving is where cheap builds give themselves away: shallow laser etching that looks like a sticker is a bad sign, while deeper relief with clean edges is a better one.
Movement
Because the original has a solid case back, the movement matters for reliability more than looks. A Miyota 9015 or a Sellita SW200 clone will keep time and can be regulated or serviced by an independent watchmaker. Unbranded low-beat movements with rough finishing are a false economy. Ask for a timegrapher photo or video and look for a rate within roughly plus or minus 10 seconds per day, a healthy amplitude, and a smooth sweep of about eight ticks per second.
Strap and bracelet
The leather version should have blue calf with even contrast stitching and a signed pin buckle. If you want the steel bracelet look, insist on solid links, the correct taper, and screw bars instead of friction pins that work loose.
Water resistance
Assume nothing. Replicas are not pressure tested, and gaskets may be dry, pinched, or missing. Do not swim, shower, or dive with one. If you plan to wear it near water, have a watchmaker pressure test and reseal it first.
How tiers differ
Sellers rarely publish honest specs, so compare builds on four axes:
- Case finishing: correct 40 mm width and thickness, sharp brushed and polished transitions.
- Dial execution: real sunburst effect, correct numeral font and spacing, centered date.
- Movement: a branded Japanese or Swiss-pattern automatic with a documented rate.
- Hardware: sapphire with genuine anti-reflective coating, solid end links, or a quality leather strap.
Entry builds usually fail on dial color and date alignment. Mid-tier builds get the case right but hide a generic movement. The best copies get close on the outside and are still not the real watch.
Pitfalls to avoid
- Stock photos or images with mismatched backgrounds. Ask for a dated photo next to a handwritten note.
- Swiss movement claims with no movement photo, even though the case back is solid.
- Sellers who call the watch genuine or original anywhere in the listing.
- Quoted water resistance figures with no pressure test behind them.
- Payment by wire, gift card, or crypto with no recourse if the watch never arrives.
- Customs risk. Counterfeit watches are seizable at the border, and you can lose both the item and your money.
- No return address, or a return window shorter than the shipping time.
FAQ
Is a fake IW327010 worth buying?
Only as a visual stand-in that you never pass off as real. It will not hold value, cannot be serviced by IWC, and may be confiscated at the border.
How do I spot a good copy in photos?
Zoom in on the dial at an angle, the date window, and the case back engraving. Then ask for a timegrapher shot and dimensions from a caliper.
Will original straps fit?
If the lugs are a true 20 mm and the spring bars are standard, yes. Ask the seller to measure before you order.
Can I wear it swimming?
No, unless a watchmaker pressure tests and reseals it. Treat the watch as splash resistant at best.
Does the date font matter?
Yes. A wrong date font or an off-center wheel is one of the easiest tells, and it is visible from across a table.
