Fits excellent on my 6.25" wrist. I had a 1:1 homage to a non ceramic sub, and I find this wears very similar, aside from the lug to lug.
The main thing to consider here is precisely the lug to lug, which is very short here, especially with the female end links. I had a 42mm before, and while could just about pull it off, the make end links effectively increased the lug to lug substantially, which made it wear too large in my opinion. For me, this is close to perfect. Plenty of men with larger wrists wear a sub, which looks similar on their wrist to many of the photos on this thread. Nobody's telling them their sub looks girly, because it doesn't.
