This Rare Annual Calendar Patek Philippe Ref# 5035R-023 Is Complete. Accompanied with its certificate of origin, instruction manual, setting pin and presentation box. This example is in excellent condition with crisp hallmarks.

This 5035R-023 is rose gold and has a semi-glossy factory black dial with applied 18k pink gold roman numerals, luminous hands and sweep centre seconds. This is a very late example with certificate of origin dated 2004. Very few have re-appeared in this sought after combination of a rose gold case with a factory black dial.

Patek Philippe's reference 5035 is 37mm. Its the first wristwatch ever to be fitted with a patented annual calendar movement. This useful complication automatically corrects the date for months with 30 and 31 days while displaying the month and the day of the week - and only requires correction once a year at the end of February. The model was in production from 1996 to 2005. Introduced in 2005, reference 5146 replaced reference 5035, now featuring a moon phase display instead of the 24 hour indication and a power reserve. Cal. 315 S QA 24H automatic movement stamped with the Geneva seal, 35 jewels, 21K gold rotor, luminous hands, sweep centre seconds, three subsidiary dials indicating day, month and 24 hour display, window for date, circular water-resistant-type case with glazed screw back, downturned lugs.
