Short answer
Omega does not make a reference 5270. The number 5270 belongs to Patek Philippe. That model is a perpetual calendar chronograph in rose gold, launched in 2011. A listing named "fake Omega 5270 copy" joins two brands that do not match. The item is a mislabeled Patek Philippe replica, a mislabeled Omega replica, or a generic watch with a made-up number.
How Omega numbers its watches
Omega uses an 8 to 11 digit reference. A Speedmaster Professional is 3570.50.00 or 310.30.42.50.01.001. A Seamaster Diver 300M is 210.30.42.20.03.001. The first digits set the case and bracelet. The last digits set the dial, case size, and movement. No Omega reference starts with 5270.
What the Patek Philippe 5270 is
Patek Philippe introduced the 5270 in 2011 as the replacement for the 5970. The case measures 41 mm. The caliber is the CH 29-535 PS Q, a manual wind movement. Two subdials carry the perpetual calendar. Retail price sits above $150,000. Pre-owned examples trade near that figure or higher.

What "1:1 copy" means in the replica market
Sellers use "1:1" to claim the case size, dial layout, and weight match the original. Common facts about these watches:
- Case diameter is copied, often within 0.5 mm.
- Movements are quartz or a modified automatic, not the original caliber.
- Pushers and subdials often do not work as the original does.
- Solid gold is replaced with steel and gold plating.
- Listed prices run from about $200 to $900.
Legal status in the US
18 U.S.C. § 2320 makes trafficking in counterfeit goods a federal crime. Penalties reach 10 years for a first offense and 20 years for repeat offenses. 15 U.S.C. § 1114 covers civil claims by the trademark owner. US Customs and Border Protection seizes counterfeit watches at ports and destroys them. Buying from abroad does not remove the risk.
Signs of a mismatched listing
Check the brand and reference against the maker's own catalog. A reference that does not appear on the maker's site is a warning sign. Check the movement type, the subdial positions, and the caseback text. Numbers on the caseback should match the reference.
What is not known
There is no public data on a production run for an "Omega 5270." No factory has published specifications under that name. Treat any claim about it as unverified.
