The reference 5039 was produced between 1996 and 2007 with an estimated total output of 500 pieces in yellow gold, such as the present piece. This traditional Patek Philippe perpetual calendar relies on the highly-praised micro-rotor cal. 240 (found on several other complicated models) and displays the date, days of the week, month, leap-year, an AM/PM indicator and furthermore incorporates a moon-phase display. Its 36mm round case displays all the classicism the brand is known for, with a the addition of a hobnail (Clou de Paris) pattern to the bezel. 

One of approximately 20 pieces to have been re-offered on the open market, the present lot stands in excellent condition and is accompanied by its full suite of accessories and documentation. The last retail price for this watch in 2007 was CHF 61'000.
