I have purchased three item, watches, and am awaiting the fourth to arrive, I am very supicious as the fourth was a low price and no other bidders !!! However I used my credit card so have some protection. DO NOT BUY UNLESS YOU USE A CREDIT CARD. I have one piece that was described as in good condition, it doesn't work ! Please be aware they appear to sting you with the exchange rate, on a 522 Euro deal I was charged ove 16 Euros, (£14) above the standard exchange rate. I see some items selling for 15,000 euros, I would be very cautious on this. Having compared prices of exclusive Swiss watches to some Pre Owned watch sites, the prices on this aution site are very similar, which means NO BARGAIN, but high risk. I recommend you use reputable sites, I think this Catawiki is like early Ebay, where many crooks are selling fake, stolen or just rubbish items they cannot sell legitimately. Conclusion, high risk, Definately not expert valuations and no bargain.
