Excellent specimen of an UNPOLISHED 16600 from Z serial with boxes, paper and tool kit. Case is very crisp with sharp bevels, thick lugs and symmetrical crown guards. The green case back sticker is still there and maintaining originality. Bracelet is fully linked here with diver extension. Warranty paper is dated in January 2007 and she is running strong with solid amplitude. Unpolished and crisp 5 digit specimens will only become harder to find in time. Few scans: Price: $9,999 via bank wire and overnight insured shipping with signature. 24 hour no questions asked return policy. For trade, I am primarily looking for Rolex 16570 Polar (M serial or newer) or 16710 in comparable unpolished and mint full set format + cash adjustment. Many references for your review and a local deal here in the NYC metro area is always great. Thanks for looking, Fred/NJ
