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."

The reference 5517 is a special military example made for the Special Boat Service of the Royal Marines in the late 1970's. Reference 5517/5513 had all the characteristic of its predecessor reference 5513 but was especially ordered from Rolex by the Royal Navy for use by the commandos of the British Special Boat Service, one of the world's most highly trained Special Forces. All inside case backs were engraved on the interior with the serial number to avoid backs being swapped during servicing. The ref. 5517 was issued until the early 1980's when the contract with Rolex expired. It is believed that the total number of all British Military Submariners, both 5513 and 5517 models, surviving from that period is now very limited.
