Patek Philippe. A Fine and Very Rare 18k Gold Perpetual Calendar Chronograph Wristwatch with Moon Phases

Accompanied by a Patek Philippe Extract from the Archives confirming production of the present watch in 1976 and its subsequent sale on November 16th of the same year.

Reference 2499, widely acknowledged as one of the world's greatest watch models ever created, has undoubtedly greatly influenced the designs of many of the most renowned watchmakers. Introduced to the market in 1950 it replaced the legendary reference 1518, the world's first perpetual calendar wristwatch with chronograph made in series.

Heir to the legendary Patek Philippe reference 1518, the world's first perpetual calendar wristwatch with chronograph function, the reference 2499 was introduced to the market in 1950 and is acknowledged to be one of the most coveted wristwatches of all time. It is undisputedly an icon of horological artistry. The reference 2499 perfectly embodies Patek Philippe's technological and artistic know-how, and has greatly inspired and influenced the configurations of many important wristwatches, needless to mention its successors the reference 3970 and 5970.

Over a period of 35 years, reference 2499 was made in four series in a total production of only 349 pieces, the majority cased in yellow gold. The rarity of this model becomes evident when considering that an annual average of only 9 watches left Patek Philippe's workshops.

Reference 2499 is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pp. 302 & 304.
