OK, now writing with a hand on my balls (this in Italy is an against-unluck gesture) as currently I have 9 (I must be going mad...) watches on going... 3 were already in UK and sent from Sead (supermirrors) so I feel confident; other 3 from Toro through Spain, 2 from Trevor through Uk (these are the most worrying for me) and finally one direct over FedEx from Andrew of Trusty time.
Some tips are to make them to ship to your office place, if possible, or to go through triangulated shipment like Toro does (and in my view better through Spain than Uk).
Finally check with the dealer if they have custom protection policy...
Enjoy your new watch and all the good vibes the entire process may give you
