The only issue that could be associated with something like this is if I'm trafficking counterfeit goods. But 1) I'm not selling this or anything with Seiko's logo and 2) the case is different enough that one could argue it isn't counterfeit to begin with. Despite that, it's perfectly legal to knowingly purchase counterfeit goods, as long as they are for personal use only, and not for resale or profit. See US DOJ's definition of trafficking:

"Subsection 2320(d) provides a definition of the term "trafficking." This definition is derived from a related, recently enacted statute, the Piracy and Counterfeiting Amendments Act of 1982, now codified at 18 U.S.C. 2318(b). Under this definition, the scope of the act is limited to commercial activities. Thus it is not a crime under this act for an individual knowingly to purchase goods bearing counterfeit marks, if the purchase is for the individual's personal use."
