There's definitely a dearth of English-language info on Casio's premium offerings, especially the older Oceanus stuff. I gather you must have purchased your wife's watch during the brief period they tried to make a go of the Oceanus sub-brand in the US?
There's all sorts of bizarre sub-variations, too. I saw a similar women's Oceanus on eBay last fall, with English-language Discovery Channel Shark Week branding, and the seller in New York was dumping it for cheap because they couldn't get the radio sync to work. Turns out it was a model that was only set up to sync with the UK and German time signals. Older Casio models also only say Multi-Band 5 as well, because, I guess, the Chinese atomic-clock broadcast hadn't been set up yet.
