Widely acknowledged as one of the world’s greatest watch models ever created, reference 2499 has undoubtedly strongly 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.
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.
Produced from 1980 to 1985, the reference 2499/100 fourth series is considered by many as being the last true vintage perpetual calendar chronograph made by Patek Philippe. Built in an 18k gold case and allied to a highly attractive dial, the timepiece is preserved in excellent overall condition. Completed with its original certificate and presentation box, such timepieces are considered extremely rare opportunities for astute collectors to acquire such a legendary reference.
Reference 2499 is generally divided into the following four series:
-First series: square chronograph buttons, applied Arabic numerals and tachymetre scale
-Second series: round chronograph buttons, either applied baton or applied Arabic numerals and tachymetre scale
-Third series: round chronograph buttons, applied baton numerals and outer seconds divisions
-Fourth series, the present watch: round chronograph buttons, applied baton numerals, outer seconds divisions and sapphire crystal
