Yep, looks like it has some problem. Tell this to the dealer, then it's a matter of your choice: he will tell you to send it back...
In such case, wearing your dress, I'd instead propose a discount on the next purchase and I'll made the watch to be serviced from a watchsmith that is replica friend (I can't suggest as I'm in Italy, and don't know where you're located). This way you'll get a proper movement (cleaned and oiled), a discount on the next purchase, and you'll not go into the hassle of sending back to China (doubling custom risks) for good money your watch remaining without it for months...
Tell the watchsmith that the clone 2824 accepts gen ETA replacement parts (only difference and only for the Seagull one is at balance bridge level, which is not interested by your problem).
PS: this obviously is worth if the piece you have is a good rep (let's say around or over 300$). The ones containing cheap 21j clone of the Miyota (normally called Asian 21j 21.600BPH) are not worth a service, in my humble opinion, as you can find a new caliber for like 35$.
