Short answer
Omega does not make a reference 5270. No Omega catalog entry uses that number. The number 5270 belongs to Patek Philippe. It is a perpetual calendar chronograph introduced in 2011 as the successor to the 5970. Sellers who write "replica omega 5270" merge two brands into one keyword.
What the 5270 is
Patek Philippe launched ref. 5270 in 2011. Case size is 41 mm. The movement is caliber CH 29-535 PS Q: manual wind, column wheel chronograph, perpetual calendar with leap year and day/night display. Metals include platinum, rose gold, yellow gold, and white gold. Production continues. Secondary market prices sit in the six-figure USD range.
Where the Omega part comes from
Omega and Patek share no reference system. Search engines return mixed results because resellers put both brand names on one listing page. Some pages use 5270 to mean a case size or an internal stock code. Omega movement numbers run in families such as 2500, 8500, 8900, and 9900. None match 5270.
What replica listings show
- Movement: Seagull ST19, modified ETA 7750, or quartz. A working perpetual calendar with leap year tracking does not appear at these price points.
- Calendar: month, date, and moonphase discs driven by an extra plate. February 29 does not advance on most examples.
- Case: 41 mm steel or plated brass. Gold plating measures 3 to 5 microns on mid-tier pieces.
- Price: USD 150 to 700 at wholesale. A service on a real CH 29-535 PS Q costs more than the watch.
Checks on a listing
- Ask for a movement photo with the caseback removed.
- Ask if the leap year indicator moves on March 1.
- Ask for case metal content, not a color name.
- Ask for the return address and the payment method.
