If buying from outside the UK, any fees for customs duties & import taxes that might be due are not included in the price of the watches...and it's the responsibility of customers to pay for these fees.
We've produced some rough guides of the approximate fees you could pay (see below). But, these figures are approximate and might be different to any actual such fees you might have to pay.
So please check with your national and/or regional government what fees like this might apply. Thank you.
