Super nice 16660 from 1985.  The patina on the dial and hands as aged to a rich pumpkin color.  The case is sharp and unpolished with clear numbers and there is a chip on the left edge of the crystal.  The bracelet appears to be original and tight with the clasp replaced with a later one.  The bezel is sharp and the insert is in excellent condition with a nice cream tritium pearl.  The movement is running strong and keeping excellent time.  Comes with original box and rolex service card guarantee from 2003
