Yes, the version is same,outer. The movement is not 7750, as I know, this is the only difference. I have very good experience with Chazingtime.
The factory is the same, I can't say whether it is exactly the same in terms of the case as I have no actual experience comparing the dimensions of A7750 and ST2555 based watches from the same factory. As for the dealer, I have nothing but praise for Ken and his staff, but that's not the question in this case.
But if you want to save 30$ going with the Seagull, now you have an option.
