The watch I purchased was an Casio G-Shock MTG-1500-1AER Collection Men's Watch I did try the watch on at my local jewellers and the price at the jewellers was 470 €. Nalevi sold it to me for 3 98€ and free postage.
I wanted to make sure of a few things before buying - authenticity, warranty etc. and I was talked through all of this by nalevi on the phone and again in an e-mail confirmation.
On the whole - my experience using www.nalevi.com was a good one and I will use them again as well as recommend them to anyone wanting to buy a watch online and save money.
