I have a similar ceramic 03-92 in Khaki, the MA-01. I love the watch you're looking at, but ultimately couldn't find a better conditioned piece at the price point I was willing to pay when I was ready to purchase. That piece you've found is what truly convinced me I wanted a B&R. So, enjoy it! Please post pics.
My 42mm B&R does seem to wear larger due to the case dimensions, even larger in comparison to my 42mm Panerai. It's simply that square case. It does not overhang my 6 3/4" wrist, however, and fits as far as I'm concerned. Best of luck!
