Whereas Patek had a bigger challenge.
I do like the 5320G and I was expecting to see a 5320P this year. Well the 240Q vs. 324Q movements question probably came down to thickness and I think the Patek did the right thing with keeping the 5740 dimensions at a thin one. Competing with the AP RO QP and the new VC Overseas QP which are both thin. The 5740 with the 324Q movement would probably make it 10+mm thick.
