What can you say other than there are other brands...
I remember buying a blue dial TT Submariner in Goldsmiths in 2010 and I was presented with the old dial version, the newly released Ceramic version and a SD for comparison. When I go in now they are completely unable to confirm anything, it's all controlled by head office don't you know.
Apart from the WIS sheep who must conform (and there are many on here), most serious buyers will go elsewhere.
