Watch sold to an enthusiastic fan of the DK10B who had been looking for this the last 2 years and had even tried Gnomon for a new piece but which was not available.
He was specifically looking for a DK10B black case with 12 hr bezel and single AR, for which my piece was a perfect match.
BTW he flew in from KK this morning to pick it up and flying back later today.
Made a new horological friend.
Thanks J and MWF.
