bonjour et bienvenue,...yes it is normal these days to get pics from the actual watch which will be send to you. Please stay with the TD's here so in case something is going wrong, moderators and members can be of help.
Once you found the watch you want, first ask the TD if it is in stock, only then pay....Most TD's will not accept paypal from new customers so look for a convenient way to make the payment. Revolut is a free prepaid creditcard which is a good option if your own cc company doesn't allow payments to CN.
