I received mine today! Haven't taken pics yet because I just unboxed it, but first impressions are great. It's nice and hefty, the ceramic is well done and has a nice matte finish. Mine is the one with the ding at 1:00 upthread, in real life it's about the size of a pinhead and I had to look hard to see it even knowing it was there. I don't find it bothersome and I'm assuming it got through their supplier's QC too.
It's comparable to the ZF in terms of overall feel, although to me it feels "larger" not so much in dimension but in presence. I think the crystal and case are marginally wider than the ZF (explains why all the photos we've seen of the BBR movement in the ZF cases have it crammed the fuck in there and the right side is overlapped by the indices) and it feels like a bigger watch although side-by-side in hand they're practically identical in terms of overall dimensions. The BBR is wider and a tiny bit taller and is ever so slightly thicker, but close enough that it's actually kinda hard to tell without setting up a stand or measuring.
All the fuss about the crystal is overblown; the AR *is* lacking and it's not the correct purple/blue like ZF but it's hardly shitter territory and I find it well within acceptable margins. My ZF RM35 v1 has similar AR, although minus the slight blue shade of the ZF. The second hand is HILARIOUSLY jumpy, though, and although I haven't wound it fully it's pretty bad at low amplitude. Winding feels fine, not gritty or mealy but there's a little resistance which I actually like. The crown clicks in and out well and feels solid, and the hands set well, with no bumps or areas of increased resistance.
The movement is impressive, although finishing isn't the best I've ever seen (some of the graining on the brushing is a teeny bit coarse) but it appears to work well and the skeletonization is cool. You can see the balance spinning, the escapement clicking around the escape wheel, and the keyless moving when you set the hands or change positions. It doesn't appear to hack alhough there is a separate hacking lever represented on the movement, and it could be just deco.
Overall, just-unboxed impressions are a light 8/10. I'm very happy with it and despite the flaws (the second hand may be a dealbreaker for some people but as long as it doesn't affect timekeeping I don't mind, and it can probably be tweaked by a competent watchsmith) it's a tremendous step forward for RM reps. We'll see what the power reserve and reliability are, as well as whether the second hand can be tweaked, but coming out of the box it's pretty damn impressive. It also comes with a fake (cheap) cardstock "RM" warranty card which is so, so, so bad that it made me laugh, which I consider a plus because comedy.
