Need a bit of advice. ! traded a watch with a friend of mine, I'm in the UK and he is in Switzerland. There was no declaration asked for when I sent it from the UK. It has arrived in Switzerland and customs there are asking him for a Proforma Invoice. What should he do? I'd be inclined to say it's a gift from a friend.... not sure if this is the right advice though! There was nothing but the watch in the box. The watch was a Panerai Daylight Chrono by the way. Suggestions would be most grateful.
