tried on one of the new Tudor bb36 yesterday because I was in the big smoke, but unfortunately didn't see the 54 in the flesh.
the new bb36s feel a lot more refined, especially with the smaller crown, less blocky case and the jubilee bracelet; feels more like an OP/ datejust now as opposed to a tool-ish diver w/ no bezel. T-fit clasp is the star of the show though at least when discussing the bracelet, that really takes the watch to a whole new level as does the in-house movement with 70 hours power reserve. also, the sunburst blue on the dial is amazing in person; again though it takes away the tool-ish feel of the original glossy blue that a lot of people love and makes it more dressy. Either way, I think they'll have trouble getting rid of old stock now that the new boys are in town. The AD I went to didn't even have the new watches on display, I had to ask them LOL...
