How to know if apple watch is stolen?

well yes i have some concerns, but the thing is product was never used, so there is no previous owners lock, because there is no any, its still sealed in a box, blacklist check is saying its clean, so, is there any other ways to check? Thank you

Its a new device, in original package, serial number on the box is listing device on Apple website, i am not concerned about the device, device is legit, i am concerned about device origin, or if its stolen. Since box is not opened device was not used, so there is no previous id on it, no one has it in search my or locked, my only question is if the device it tracked by police, some store or whatever place could be stolen from, if thats the case.

its not online purchase, i can meet seller face to face, so empty box, rewrap or so its not an option bc you can see that, my only concern is that it was stolen from some store, post office or whatever place can it be stolen from in original box brand new, and is that someone looking for it or can it even be found, I called two Apple stores, and their website, and Apple said no, if user didn't use it or connect it to his id, Apple cant do anything to help them find it or track it, only option is if it was reported to police as stolen and police asked network provider to track it once connected to it.

I did that, its showing ID number, model, date of purchase, and type of warranty and date of ending.

But i agree, better safe than sorry. Thank you

Of course, thank you.
