This watch is a highly attractive and rare stainless steel example of the celebrated reference 565, preserved in very good overall condition, its two-tone silvered dial combined with the very technical yet smooth case proportions adding up to a perfect look. To the best of our knowledge it has never been offered in public before.
Reference 565, the first large water-resistant watch featuring a two-piece case with screw back and dust cover, was available with either subsidiary or sweep centre seconds. The first series was launched in 1938 with calibre 12'''120, the second with calibre 12’’’400, such as the present watch, in 1950. The centre seconds version featuring a calibre 12 SCi movement started in 1939, replaced by the new calibre 27 SC as of 1949.
The timelessly modern design of reference 565 served as inspiration for the creation of the 2006 stainless steel inaugural reference 5565.
Various examples of reference 565 are illustrated in Patek Philippe Steel Watches by John Goldberger, pp. 165 – 195.
