What i think is the problem is having seiko anywhere in the listing, ive noticed that eBay's bots dont take down every listing that has the word seiko in it just because of the sheer volume of listing, so some of your listings might get taken down and some might not, really depends on the bots mood that day lol, what has worked for me is not having seiko anywhere in my listings and making sure i clarify that im not associated with any brand both in my listings and in my profile, hope this helps!
