Obviously not fitted with the original Seiko bracelet - google images for 7A28-7030.
7Axx's are not faked (yet), though there are plenty of cobbled together Frankens on eBay to catch the unwary buyer.
The only thing to watch for on this particular model is fake repro' bezel inserts (meant for the 6139-6002, but they'll also just fit these). The bezel insert on this one looks original. A tidy (if overpriced) example - apart from the lack of bracelet.
