Need some GMT advice..

[120Rolex]

Hi Rolexers,

After some consideration, I think I'll be making the GMT my next purchase. I've surfed a lot of sites and I'm just a bit confused.

What are the vintages / advantages of the coloured bezels (coke, rb, pepsi)?, is there a particular model that stands out?

Also, did this watch ever come in black or is this bogus?

Would love to also hear about general opinions form owners..

Thanks so much,

J
