Need help - are these the same watch? (GMT)

[Kiterpete]

Looking to buy a Pepsi GMT have purchased in the past from Trusty (Andrew) and Watcheden (Tony/Sarah) Watcheden tells me this watch:

is better quality than Andrews:

Which is why, apparently, is why Watcheden wants more money - there isn't much of a price difference but seeing how I would like the better of the 2 reps I'm now confused. Can someone with more knowledge about Rolex help out please - or recommend another dealer/deal.

Much appreciated
