I measured my wrist and the L2L of 48.6 would just about not overhang. But yeah because I want to be on the safe side I did go with the 36mm.I think the 40mm version is too big for a 6,25" wrist. The 48.6mm L2L is not insignificant. Of course some people don't mind having the lugs overhand their wrist, but I do.
I'm actually interested in seeing how it looks. (I know, historically big watches, yada yada )I am almost sure it is too small. I am wearing larger watches with less wrist size.
