Short answer
"Fake grand complication 720.025" is a search term buyers use for replica versions of a high complication Swiss watch sold under the product code 720.025. A grand complication carries at least three functions beyond timekeeping, such as a split seconds chronograph, a perpetual calendar, and a minute repeater. The code 720.025 does not appear in Patek Philippe's public catalog of references, so the number works as a seller code, not a factory reference number. Treat any listing that uses it as an offer for a replica.
What the number covers
Listings filed under 720.025 show a round case with a perpetual calendar dial: day, date, month, leap year indicator, moon phase, and a chronograph. Case sizes in those listings run from 40 mm to 42 mm. Photos change between sellers, and the same code can point to different builds from different factories. The number groups a dial layout and a case shape, nothing more.
Movements seen in this class
Two movement families appear. The first is a modified Chinese automatic or hand wound base with added calendar modules on top of the main plate. The second is a decorated automatic movement with a fake skeleton rotor and a calendar that advances by pusher, not by gear train. Working minute repeaters in replicas are scarce. Most listings that name a repeater show a decorative slide or leave the function out of the photos. Ask for a video with sound before you pay for any repeater claim.
Checks before payment
- Case thickness. A stacked perpetual calendar module adds height. A 9 mm case with a full calendar dial is quartz or a thin automatic with a printed dial.
- Calendar behavior. On a real perpetual calendar the date jumps at midnight and tracks February. On a pusher set copy you adjust each function by hand.
- Movement photo with the case back off. Finishing, engraving, and jewel count are visible in a clear photo.
- Font and print on the dial. Blurred text under a loupe is the first visible tell.
- Payment method and return window. Card payment and a written return term reduce risk.
Price bands
Listings in this category run about $200 to $600 for quartz or basic automatic builds, and $600 to $1,500 for decorated automatic movements with working calendar modules. Anything above that range needs a movement photo and a stated service history. The genuine watches that these replicas copy trade for six figures at auction, which is the reason the replica listings exist.
Legal position in the US
Counterfeit watches are illegal to traffic in the United States. Import shipments face seizure by Customs and Border Protection, and sales carry civil and criminal exposure. Buying for personal use does not remove the customs risk on the parcel.
If you already own one
Check the movement against the listing photos, weigh the watch, and test each calendar function at the month change. A repeater slide that moves without sound means the gongs are missing or the slide is decorative. Resale value for replicas is low and no service network supports these movements.
