Picked up the BB54 last year and it has been my main watch, outshining my 5 digit Sub and 38.5mm Aqua Terra. It's a perfect size, weight and is solidly built. Plus I haven't had any major urges to buy something new 18 months down the line which says a lot!!
The BB54 is practically perfect. The proportions, it’s slim, it’s accurate, and the adjustable clasp is just the best (I also have the Mark XX which has a similar clasp but slightly less range.)
The only potential downside is if you don’t like the vintage styling. Hopefully they bring out a version this year with a more modern look (something like the Blue and white BB58.)
Nice video. I've got a BB54 and have wondered about the BB58. I live the watch, and you are absolutely correct that it doesn't wear like a 37mm watch. That lug to lug is a big deal. One key point about these is historical. The BB54 is a very, very close homage to the first Rolex Sub of '53, and the first Tudor Sub of '54. It is the closest we can get to a vintage watch made to today's higher manufacturing standards, imho. All the best.
