Reference 5726 was launched in 2010 in stainless steel only, with a leather strap. In 2012, Patek Philippe began production of the reference 5726-1A; which came with a stainless steel bracelet, such as the present watch.

With further interest, the present lot features a dual signed Tiffany Dial, representative of the longstanding relationship between Patek Philippe and Tiffany & Co.

Tiffany & Co.
The celebrated house of Tiffany & Co., founded by Charles Lewis Tiffany (1812-1902), opened his first store in New York in 1837. Ten years later, his catalogue incorporated French watches and clocks. Tiffany probably became acquainted with the quality watchmakers Antoine Patek and Adrien Philippe at the Great Exhibition in London in 1851, and three years later agreed to import Patek Philippe pocket watches into the US. In 1868, Tiffany started advertising its own dial names. By 1874 Tiffany had become a veritable Swiss watchmaker, producing timepieces by the lake in Geneva at 10 Grand Quai, today Patek Philippe's prestigious Salon on the renamed Rue du Rhône. In that same year, Charles Tiffany opened an ultra-modern factory on Place Cornavin and shortly after, his company was acknowledged as the leading watch and clock retailer in the US, alongside its substantial jewelry business.
