Rolex Cosmograph Daytona Solid 18K Yellow Gold 40mm Watch (Model: 16528) W/Zenith Movement, Inverted 6 Champagne Dial & Factory Diamond Markers in Box - This handsome, investment quality timepiece was made by Rolex, and is the highly coveted Cosmograph Daytona 16500 series. This particular configuration was first introduced in the 1980's and had several upgrades to the previous model including the famous automatic self-winding Zenith movement. The watch also features: 40mm solid 18k yellow gold case, rare champagne dial with (8) factory diamond markers, scratch-resistant sapphire crystal, 18k yellow gold bezel with tachometer engraving and solid 18k yellow gold Oyster bracelet with polished center links. This watch is truly a collector's dream, as there were only a few of these models released each year, and with the original "inverted 6" champagne diamond dial this model is nearly impossible to find. This watch has recently been serviced and is in perfect working condition. It will come housed in a box. The watch measures 8.25" in circumference, and is in absolutely stunning condition. A serial number lookup suggests that this piece was made in 1991. Serial #: N11XXXXX. These watches are a must have for the advanced collector, or someone who wants the best watch. You cannot find these watches anywhere, especially in this condition.
