Short answer
"Replica Omega 3320" is a phrase used in counterfeit watch listings. It suggests a fake Omega chronograph built around Omega's calibre 3320 movement. No counterfeit sold under that label contains a genuine Omega 3320. The movement inside is a Chinese or generic clone, such as a Seagull ST19, an Asian 7750, or a quartz module hidden behind a decorated rotor. The number is marketing text, not a specification.
What the real Omega 3320 is
The 3320 belongs to Omega's 33xx family of automatic chronograph movements, introduced in the early 2000s and used in Speedmaster and Seamaster chronographs. The family was developed on a Frederic Piguet chronograph base, and later versions added Omega's co-axial escapement. A genuine 3320 is finished to Swiss standards, runs at a fixed beat rate, and is serviced through Omega or an authorized watchmaker with access to parts. That combination is why the movement cannot appear in a counterfeit at any realistic price.
Why the label appears in listings
Sellers borrow real calibre numbers to sound technical. A buyer who sees "3320" assumes a genuine Swiss movement and a higher grade of replica. The photos usually show a caseback with engraved text, never the movement itself, or a stock image of a genuine movement that is not inside the watch being sold.
How to check a watch sold as a 3320
- Ask for a clear photo of the movement with the caseback removed and the rotor turned away from the balance.
- Compare the engraving on the bridges to Omega's published layout, including font, spacing, and jewel count.
- Check the subdial layout and pusher positions against the genuine reference the seller claims to copy.
- Time the watch over 24 hours. A genuine chronograph movement holds a steady rate, while clones drift and the chronograph seconds hand stutters.
- Confirm the price. Genuine 33xx-based watches sell for four figures, so an asking price in the low hundreds signals a counterfeit regardless of the label.
US legal and practical risks
Counterfeit watches are illegal to import and sell in the United States. US Customs and Border Protection can seize and destroy shipments, and trafficking in counterfeit goods is a federal offense under 18 U.S.C. § 2320. Buyers also lose everything after the sale: no warranty, no service parts, and no recourse when the movement fails. Many counterfeits use plated brass cases, mineral glass, and movements that stop within a year.
Better alternatives
- A used genuine Omega or a comparable Swiss chronograph from an authorized dealer or a reputable pre-owned seller.
- Homage brands that use their own designs and Seiko or Miyota movements, which are legal and serviceable.
- Factory-serviced vintage chronographs, which hold value and can be repaired.
