I'd say all such comparisons are closer than the price would suggest. However, there is a step up that is expected with price and access to more than expensive materials etc.
I love my Speedbird GMT, and my double dome 29b, and for me those watches offer so much more than the original selling price suggests.
So, in my opinion the Bremont is better made (maybe finished is the better term). No idea about the differences or similarities in movements between, but it's not that much better made.
Similarly, my Patek is not 5 times better built than my Rolex Submariners but that's roughly how many times more the purcgase price was for me, albeit I'd thankfully bought the Subs years earlier.
