Up for grabs is a Rolex Datejust, cased in 18kt yellow gold, circa 1977, fitted with a very rare black “onyx” dial. Stone dial Datejust and Day-Dates have soared in popularity, adding a little variance to your normal fare dials of the Datejust and Day-Date models. This particular Rolex Datejust is in great vintage condition. The case appears lightly polished, but retains thick and even lugs and strong lines. The onyx dial is perfect, with no cracks or blemishes. The watch comes fitted on its original Rolex hidden-clasp Swiss bracelet, with 3 removable links and light stretch.
