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 1997 Patek Philippe created the reference 4864, a wristwatch for widely travelled ladies. This watch is based on the ref. 2597, the original travel time from the firm, with a calibre designed by Louis Cottier. The lady's travel time combines the classic and elegant design of the Calatrava with two independent functioning time zones, one of them indicating 24 hours. 
 The two tone dial and diamond-set indexes of this particular watch bring a feminine tone to the model.
The production was ceased in 2005.
