I purchased a watch from Nalevi.com 2 weeks ago, the watch took 5 days to get to me from point of purchase and it arrived with box, paperwork and watch in perfect order. The store was very easy to use and the payment section was user friendly - I tend to freak out at the payment part as I do not buy online often.
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.
