Hi Seb,
I have been thinking about your 'techy' comment for a few days and I agree. People who like larger watches shouldn't buy the 7057 assuming it is just a larger 7027. It has a completely different 'vibe' on the wrist and whereas the original 7027 tapped into a bygone age and used A.L. Breguet's legacy to full effect, the 7057 is much more modern. It depends what you are looking for, I guess, but it doesn't quite fit with a watch called "La Tradition".
