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."

Introduced in 1928 this movement, manufactured for Rolex by Hermann Aegler, was rectangular and had its winding barrel at one end and a large balance at the other. This allowed a larger barrel, and therefore longer autonomy (up to 58 hours). At the same time, the layout allowed a larger balance in a small watch thereby increasing accuracy. The Rolex Prince was often called a "Doctor's watch" or "Nurse's watch" because the relatively large subsidiary seconds dial was easily readable and useful for functions like pulse readings. Rolex Prince models continued until the mid-1940s. The classic dress watch design was a great success and the Prince range remains highly collectible today. Available in a variety of styles, examples with jumping hours are especially rare.
