Replica Omega caliber 9800: short answer
'Replica Omega caliber 9800' is a seller label. It does not mean the watch contains an Omega movement. Genuine Omega caliber 9800 is a Master Chronometer movement made in Switzerland. Replica watches sold from China at $200 to $600 use Chinese-made automatic movements. Some sellers decorate those movements to look like Omega calibers. The decoration does not change the movement origin or performance.

What the genuine Omega 9800 is
Omega lists the 9800 as a Master Chronometer automatic movement. Public spec sheets list a co-axial escapement, a 60-hour power reserve, and magnetic resistance to 15,000 gauss. The movement carries METAS Master Chronometer certification. Omega publishes the test criteria. A genuine 9800 movement is not sold as a loose part to replica factories. Omega controls parts distribution through its service network.
What replicas use
Most replica Omega watches use movements from Chinese factories. Common examples include the Hangzhou 6460, the Seagull ST2130, and the Asia ETA 2824 clone. These movements run at 28,800 vibrations per hour. They do not have a co-axial escapement. They do not carry METAS certification. A replica seller may print '9800' on a rotor or caseback. The print is cosmetic.
How to check a replica movement
Ask the seller for a photo of the movement with the rotor removed. Look for a balance wheel frequency of 28,800 vph. Omega lists a silicon hairspring and a free-sprung balance for Master Chronometer movements. Replica movements often have a regulator index and a metal hairspring. Ask for a timegrapher photo. A genuine Master Chronometer runs within 0 to +5 seconds per day. Most replicas run outside that range. These checks are not proof. Only an Omega service center can authenticate a genuine movement.

Price and legal risk
Replica Omega watches from China sell for $200 to $600. A genuine Omega with caliber 9800 sells for $5,000 and up. The price gap is a signal. U.S. Customs and Border Protection seizes counterfeit watches. Importing counterfeit goods is illegal in the United States. The FBI warns that counterfeit goods can fund organized crime. A replica watch is not a gray-market watch. It is an unauthorized copy.
