- RETAILED BY GOBBI: AN EXTREMELY RARE YELLOW GOLD PERPETUAL CALENDAR CHRONOGRAPH WRISTWATCH WITH MOON PHASES AND REGISTERS
REF 2499 THIRD SERIES MVT 869447 CASE 2700399 MADE IN 1972
- yellow gold
- diameter 38 mm
Produced from 1950, reference 2499 is recognized as one of the most important wristwatch models made by Patek Philippe. The 2499 was the successor to the legendary reference 1518, the world’s first perpetual calendar wristwatch with chronograph to be produced in series. The 2499 was replaced in 1985 by reference 3970.
With only 349 pieces made in total, representing an average of just nine pieces per year, reference 2499 holds a distinguished place among the firm's exceptional perpetual calendar chronograph wristwatches. It is a highly refined model and one that was made with the utmost attention paid to every detail of its design.
Reference 2499 underwent four major evolutions over its 35-year production run:
- The first series was distinguished by its square chronograph pushers, applied Arabic numerals and, in most examples, a tachometer scale
- The second series introduced round chronograph pushers, either applied baton or applied Arabic numerals and tachometer scale
- The third series, to which the present example belongs, was produced from 1960 until 1978, it is distinguished by the clarity of its dial’s design, with no outer tachometer scale.
- Finally, the fourth series, also referred to as reference 2944/100, differed from the third series by the addition of a sapphire crystal.
Reference 2499 is illustrated, along with explanations of the perpetual calendar and chronograph functions, in Huber, M., and Banbery, A., Patek Philippe Wristwatches, Vol. II, Second Edition, pp. 298-302.
