Rolex grey market VS Brexit

[joshpatto]

So the majority of grey market Rolex's come from overseas. Some grey markets are offering an "International Rolex Warranty" with the watches they sell. Now I presume that's the standard Rolex warranty that is remaining with the watch but how will this affect us in the UK if we need warranty work doing to our time peice?

So let's say I buy a 2016 Sub from John at Grey market jewellers in London. John got his Sub from an AD in Italy. John is selling this Sub with the remaining Rolex warranty (which originated in Italy). My Sub is losing time quite a lot so I take it to a Rolex dealer UK with my warranty card (to remind you - originated in Italy)... Will their be any problem having this work done even though we are now out of the EU? Surely not I thought but my local AD told me otherwise!!!

Apparently he's heard rumours that this will be the case. Now is this usual salesman talk trying to seal a deal or has anybody heard the same thing?
