The short answer
There is no legitimate market for a counterfeit Patek Philippe 5370P, and no replica sold under that name is worth your money. Listings that promise a 1:1 Swiss super clone of reference 5370P are selling a mass produced watch with an ordinary chronograph movement dressed up to resemble a split seconds caliber. These watches fail on weight, thickness, dial material, and movement architecture, and buying one leaves you open to customs seizure, payment fraud, and zero recourse. If you want the 5370P experience, buy a real example through an authorized dealer or a major auction house, or spend the same money on an honest watch from a brand that designs its own products.

Why the 5370P attracts fakes
Reference 5370P is a platinum split seconds chronograph with a grand feu enamel dial and the in house CHR 29-535 PS caliber. It is one of the most technically demanding watches in the Patek Philippe catalog, and it sells in the high six figures on the secondary market. That combination of fame and price is exactly what counterfeiters look for. The problem for them is that a rattrapante, also called a split seconds chronograph, needs a second chronograph wheel, a split seconds lever, an isolator, and a column wheel arrangement that copiers cannot reproduce at replica prices. So they do not reproduce it. They build a standard chronograph, add decorative plates, and use the 5370P name to sell it.
What to look for
Weight and metal
Platinum is about 2.7 times as dense as stainless steel. A platinum cased 5370P feels heavy the moment it leaves the box, and the case takes on a soft grey white tone rather than the bright white of steel or rhodium plated white gold. Fakes are usually steel, brass, or zinc alloy with plating. They feel light, and the plating wears through at the lugs and crown within months.
Thickness and proportions
The real 5370P measures 41 mm across and roughly 13 mm thick. Counterfeits built on a generic chronograph base usually run 15 mm or more, so the watch sits high on the wrist and the case sides look slab like. Lug shape, crown size, and pusher placement also drift on fakes, and the split seconds pusher at 4 o'clock is often present but does nothing.
Replica Patek Philippe 5370P Watch: A Comprehensive Guide
The movement
Ask for a movement photograph through the sapphire caseback. The CHR 29-535 PS shows Geneva stripes, black polished steel parts, chamfered bridges, gold chatons, and a large balance running at 4 Hz with about 65 hours of power reserve. Fakes show stamped bridges, glued on decoration, rough screws, and a rotor or gear train that does not match the layout. If the seller refuses a movement photo, stop there.
The dial
Grand feu enamel is fired at high temperature and has a deep, glassy surface with no grain or plastic sheen. Subdials sit at 3 and 9 o'clock, with an instantaneous 30 minute counter and small seconds. Fakes often show a date window, a printed grid, or subdials in the wrong positions, and the printing frays under a loupe.
Hallmarks and paperwork
Swiss platinum carries a dog head hallmark that steel and gold do not. The 5370P also carries the Patek Philippe Seal, a matching movement and case number, and a certificate or archive extract. Fake sets come with photocopied papers, mismatched numbers, and no service history.
Parameter bands to check
- Case diameter: 41 mm real, 40 to 43 mm on typical fakes.
- Case thickness: about 13 mm real, 15 mm and up on fakes.
- Case metal: platinum with a dog head hallmark, against steel or plated alloy.
- Movement: CHR 29-535 PS manual wind split seconds, 4 Hz, about 65 hours of reserve, against a basic automatic chronograph.
- Dial: grand feu enamel with two subdials, against painted metal or lacquer with extra apertures.
- Price asked: fakes sit in the low hundreds to low thousands, which is a fraction of a percent of a real 5370P.
Common pitfalls
- Social media sellers who take crypto or wire only, then vanish or ship a different watch.
- Photos borrowed from auction listings. Run a reverse image search before you talk money.
- Claims of a Swiss made clone that uses real Patek parts. There is no such supply chain.
- Customs risk. Counterfeit watches are seized at U.S. ports and you lose both the watch and the money.
- Trademark counterfeiting is illegal in the United States, and trafficking carries criminal penalties.
FAQ
Is a super clone 5370P close to the real thing?
No. The split seconds complication is the whole point of the reference, and no replica at that price level contains a working rattrapante.
Can a watchmaker tell the difference?
In seconds. Weight, thickness, movement finish, and hallmark stamps settle it without opening the caseback.
What does Swiss made mean on a fake?
Nothing enforceable. It is a printed word on a dial, not a statement of origin or quality.
Where should I buy a real 5370P?
An authorized Patek Philippe dealer or a major auction house with a documented provenance chain. Budget for a pre purchase inspection, and confirm the movement and case numbers in writing.
