The Rolex Datejust was produced in the late 1970s and has a fascinating design set.  At its core, this classic Rolex dress watch features a waterproof Oyster case, a self-winding Perpetual movement, and an automatically changing date display.  It even sports the classic 36mm case and famous 5-piece link Jubilee bracelet.  The bezel, which features a unique engine-turned texture, sets this model apart from other Rolexes and makes it particularly collection-worthy.
