Introduced in 1999, the reference 5036/1 is an evolution of the first Patek Philippe annual calendar watch model Ref. 5035.
Patek Philippe 5036/1 comes with two additional functions (power reserve and moon phases) along with the patented annual calendar complication. It houses the caliber 315/199 S IRM QA, a self-winding movement featuring 37 jewels.
Its dial features two sub dials for the day and week displays, power reserve indicator at 12 o’clock, and a moonphase display above the date aperture at 6 o’ clock. It should be noted that the text “PATEK PHILIPPE GENÈVE” is placed at the lower part of the dial instead of upper side.
Patek Philippe produced yellow, white and rose gold versions of this 37mm watch. All of them were supplied with matching metal bracelets with double folding clasp.
