Important Notice regarding importation into the United States of Rolex watches
Sotheby's cannot arrange for the delivery of Rolex watches to the United States because U.S. laws restricts the import of Rolex watches. The buyer or a designated agent may collect the property in the country of sale."

In the mid-197🍷0s, Rolex developed their own quartz movement caliber and introduced it in a cutting edge angular case, Ref. 17000. This model, the Oysterquartz Datejust, was rather unpopular at the time of its release, however collectors were instantly꧅ captivated by the newly styled shape of the case with a more geometric look.

The present model, 🥂Ref. 1530, was released around this time in the same iconic Oysterquartz case, but with an automatic movement, cal. 1570. Today these models are collectible bec♏ause of their limited production run and the fact that their design is still a departure from the standard Rolex look.
