Is Citizen Eco-Drive BN0100-51E Watch Worth Buying Online?

I usually wear Seiko watch. But currently i'm thinking of changing my watch. As I searched on internet i found Citizen BN0100-51E at http://www.direcbargains.com.au. The watch looks cool, seems very cheap, but never bought online.

So is it secure to buy this watch online and is it worth buying from this site? Please recommend me, if there is any other cool watches available.
