What does "fake Big Pilot IW5105" mean?
A "fake Big Pilot IW5105" is a replica of an IWC Big Pilot's Watch sold under a code that is not a complete IWC reference number. IWC writes references as IW plus six digits, so IW5105 is a fragment. Any listing built on that fragment is selling a copy, and the short code makes it hard for a buyer to compare the watch to a real model.
Fake Big Pilot IW5105 Price: What a Replica IWC Big Pilot Really Costs
Sellers trim reference numbers for a reason. A partial code looks official, resists a quick search, and cannot be matched to a spec sheet or a retail price.
Is IW5105 a real IWC reference number?
Not as a full number. Modern IWC references carry the prefix IW plus six digits, which is why genuine Big Pilot codes look like IW500912, IW501001, or IW329301. A code that stops at IW5105 is a fragment of a reference, not a reference.
IW5105 is probably shorthand for a six digit family such as IW5105xx. That family could point to a real watch, but the listing still needs to print all six digits. Without them you cannot match the watch to a catalog entry.
How IWC reference numbers work
The first digits after IW point to a model family. The last digits mark the variant: case metal, dial color, strap or bracelet, and sometimes the market.
Two watches from the same family can differ in case metal, dial, and movement. Four digits give you the family and nothing else, which is exactly why a vague code survives in replica listings.
What does a replica Big Pilot copy well, and what does it miss?
Case shape and dial layout are the easy parts. A decent replica gets the 46mm case, the oversized conical crown, the clean dial, and the riveted strap close to the original.
The hard parts are the movement and the finishing on the crown, caseback, and buckle. That is where the money goes, and where cheap copies show themselves.
The movement
The classic Big Pilot runs a seven day in-house caliber with a power reserve display on the dial. Copying a long power reserve costs real money, so many replicas fit a standard automatic and drive the reserve hand with a separate gear or leave it fixed.
Simple test: wind the watch fully, note where the reserve hand sits, and check it 24 hours later. A working seven day reserve barely moves in a day. A fake reserve hand drops fast or never moves at all.
Case and dial details
Crystal quality, crown threads, and lume are the usual weak points. Ask for a macro photo of the crown and a shot of the dial in a dark room after charging the lume.
Weight tells you plenty. A 46mm steel Big Pilot feels heavy in the hand. Copies with thin cases and hollow parts feel light.
How do you read a replica listing before you pay?
- Ask the seller for the full reference: all six digits after IW.
- Pull the official spec (case size, thickness, crystal, water resistance) and compare it to the listing.
- Request a short video: seconds hand running, crown pulled to set the time, date flipping.
- Ask which movement is inside and whether service parts exist for it.
- Get the return policy in writing and pay with a method that allows a chargeback.
What are the common tells on a fake Big Pilot?
- Power reserve hand that never moves, or moves when you turn the crown.
- Date window cut too wide, or a date font that sits too round.
- Crown too small, or threads that feel coarse when you screw it down.
- Dial printing that sits thick and raised under a loupe.
- Caseback engraving that is shallow or off center.
- Strap rivets that are glued instead of sewn and set.
- A case that feels light for its size.
What is the difference between a "super clone" and a standard replica?
"Super clone" is a seller term, not an industry standard. In practice it means a copy built around a movement styled to look like the original caliber, with case and dial work to match.
Two sellers can use the label for watches of very different quality. Ask for specs, photos, and the movement name instead of trusting the label.
What should a replica Big Pilot cost?
Prices cluster in three rough tiers. Anything far below the tier that matches the quoted specs is a warning sign, not a bargain.
- Entry, under about $120: stamped case, basic movement, printed dial.
- Mid, $200 to $350: cleaner case finishing, sapphire crystal, a reliable clone movement.
- Top, $400 and up: correct proportions, decorated movement, strap and buckle that match the original.
Questions people ask about replica Big Pilots
Is it legal to buy a fake watch in the US?
Selling counterfeit goods is illegal in the US. Buying one for personal use sits in a gray zone, but customs can seize a counterfeit watch at the border and you lose the money. Treat the risk as real.
Can a watchmaker tell a replica Big Pilot from the real one?
Yes. The movement is the giveaway: an in-house IWC caliber with a long power reserve looks nothing like a generic clone. Caseback engraving and crown threads are the second check.
Will a replica Big Pilot hold value?
No. Replica prices fall the moment you open the box, and resale stays inside the same gray market that sold it. Buy one as a wearer, not as an asset.
Does a higher price always mean a better replica?
No. A mid tier copy with a serviceable movement can outlast a top tier copy with a fragile decoration plate. Ask about service parts before you ask about finishing.
