I have been lucky enough to come by a very nice pair of 1133 Greys and have never owned a black sub register variant before. I had always wondered about the subtle (or no so subtle actually) differences between the dials and their finishes.

I think this provides proof that the colour is quite different and so to the grain, with more grain on the early Grey/Grey variant (closer to the grain of metallic 1133b trans/chronomatics). I say early as i'm farily sure the G/B is a early to mid 70s dial and like the pictures in the 1970 catalogue (one on the cover G/G with recessed subs with blue lume) the G/G is the Grey version that came to market first at the same time as the 1133b metallic dials so late 1969 and 1970s.

They are both beauties however i prefer the metallic dials with grain in them so for me the G/G just edges out the G/B due to this. However perhaps one day we will unearth a Grey dial with the grain with recessed black subs...not painted subs?!
