Pre-owned but like new!! I have used it about 10 times only!! Great Automatic LIMITED EDITION watch for the price!! Seiko Prospex Automatic LIMITED EDITION SRP579 SRP579K1 SRP579K Men's Watch The Prospex version of the Monster is actually a more refined Monster. It’s given a more intricate dial finishing and tad less the blinding glow. It tames the Monster for the indoors. There’s the compass function all right, earning it the name Land Monster and its limited edition Black Monster is not here for too long. Its black, hard coat and the 4R36 powerhouse entices lot more than you think.
