Reference 1665 was the first wristwatch designed for use in saturation diving, fitted with a Rolex patent valve in the band and guaranteed waterproof to 610 meters depth. The valve was first developed on the Submariner model and allows helium and other gases to escape, enabling the watch to stand compression. For examples of the reference 1665, please see lots 2434 and 2435 in this sale.THE PROPERTY OF AN IMPORTANT ITALIAN PRIVATE COLLECTOR
