Patek Philippe Tiffany & Co. yellow gold perpetual calendar chronograph wrist watch with moon phases

Patek Philippe Tiffany & Co. yellow gold perpetual calendar chronograph wrist watch with moon phases
Produced from 1950 until 1985, Ref. 2499 is recognized as one of the most important wristwatches made by Patek Philippe. The successor to Ref. 1518 and the predecessor to Ref. 3970, Ref. 2499 holds a distinguished place among the firm’s exceptional perpetual calendar chronograph wristwatches. With only 349 pieces made in total, or an average of only nine pieces per year, it is an extremely rare piece and one that was made with the utmost attention paid to each detail.
Ref. 2499 underwent four major evolutions during its 35-year production run. Square chronograph pushers and a tachometer scale distinguish the first series, produced between 1950 and 1960. The second series, produced between 1955-1964, introduces round chronograph pushers. A simple dial design designates the third series, which Patek produced from 1960 to 1978, and a sapphire crystal demarcates the fourth series, so called the 2499/00, produced between 1978 and 1984. The present lot represents the third series, which was produced between 1960 to 1978.
Patek Philippe and Tiffany & Co. share a remarkable history dating back to a handshake agreement between Antoine de Patek and Charles Lewis Tiffany in 1851. The two met each other during Patek’s tour in America and held a deep respect for each other due to their mutual commitment to an exceedingly high level of craftsmanship and quality in their respective fields. Tiffany formalized their handshake agreement in 1876, and the two firms have had a successful relationship which continued to grow stronger for years to come. Today, Tiffany & Co. remains the most recognizable retailer in partnership with Patek Philippe, and thus, the most important firm that still co-sign the dial of a Patek Philippe watch.
