Mxxxxxx-case number stainless steel Daytona Cosmograph model 116520 with white dial on Oysterlock bracelet ref 78490. Comes with original boxes, booklet, swing-tags and February 2008 Rolex warranty card from Ernest Jones. Extremely smart watch, just a TINY mark on the edge of the bezel between 7 and 8 o'clock. The NEW equivalent is now £6,310 so this is a great opportunity to buy the legendary steel Daytona without having to wait for years or pay a silly premium!
