MK Personal Collection The present lot is part of a larger privately held collection and is intended for exhibition purposes only. Rolex Ref 6238 Pre Daytona Oyster Chronograph Wristwatch "Fuerza Aerea del Peru" Circa 1966. This very fine men's steel Rolex Cosmograph Pre "Daytona" has a three body construction case and screwed down dedicated case back engraved "Fuerza Aerea del Peru" Peruvian Air Force Serial #1,104,XXX. The watch has the original silver painted dial with applied steel baton indexes and luminous dots, subsidiary dials for the seconds, the 12-hour and 30 minute registers, outer tachmometer scale, luminous steel baton hands, Cal 72B Rolex Chronograph movement with rhodium plated 17 jewels, straight line lever escapement, monometallic balance, shock absorber, self compensating free spring Breguet balance spring. The watch is in overall good condition. It just needs a polish. Produced from approximately 1960 to 1967, the Rolex reference 6238 is a perfect embodiment of the timeless chronograph. Referred to as the “Pre-Daytona” by collectors, the reference 6238 shares similar case size, pushers and baton hands as its contemporary, the first Cosmograph Daytona reference 6239. However, while the Cosmograph Daytona always features a two tone dial with either black with silver sub dials or vice versa, the reference 6238 was offered only with a monochromatic dial. Marking the end of an era, the 6238 was also the last Rolex chronograph to feature a smooth bezel and a graduated tachymeter scale printed on the dial. Rolex’s later Daytona models would all display the scale on the bezel.
