Reference 1463, along with the split seconds reference 1563, is the only vintage, water resistant chronograph wristwatch that Patek Philippe produced. The case was designed by Frères Borgel, Taubert & Fils when the company was known in the late 19th century as one of Geneva's finest case makers specializing in water-resisting cases. Manufactured from approximately 1940 to 1969, the reference is playfully dubbed "Tasti Tondi" due to its large waterproof round pushers.

Close inspection and research reveals that the present watch was originally sold in the United States, confirmed by the HOX export mark on the balance bridge of the movement but also by the tachymetre calibrated in miles rather than kilometers, a rare feature reserved for Patek Philippe chronographs intended for the U.S. market.

The overall look of this beautiful timepiece with the raised hard enameled signatures and scales is further enhanced with the elusive Breguet numerals, making it one of the most desirable configuration which is highly sought after by collectors. According to research, so far only 17 known other pieces in yellow gold with Breguet numerals dial are known in the market which adds enormously to its appeal and collectability.
