Well, the plain fact of replica collecting is that even "quality" movements in these watches are often contaminated by dust and hair, or need oiling. The movement in your "new" watch could be years old. (stored in a warehouse somewhere before being used)
The most inexpensive and time-efficient way of dealing with a new rep that has some sort of minor issue is to have it fully serviced by a watchmaker on the Forum. At that point, you are good to go for 5 years (watch oil slowly evaporates)
If you contact your dealer and he wants you to send it back at your expense (he will) then you are looking at 2 months turn-around and the cost to ship it registered mail to China, with possible seizure.
Altho most Gen watch owners never service their $5000 wonders, they are totally wrong in doing so .. 3 to 5 years is standard, and it's no different for replicas.
post a pic of the movement. we can tell plain as day if it's a a21j or a clone or a gen eta.
