I'm in the market for a new luxury watch... looking at high end premium Swiss brands is just not to my budget... so had a search for micro brands, and some are looking very nice, but their background and aftermarket value looks shady... so I decided to stick with a brand I love and trust and that's CASIO... now I didn't know CASIO had anything to do with Grand SEIKO so this OCW-S100 Oceanus was something that really made me want it after reading about that!
