With Patek Philippe Extract from the Archives confirming production of the present watch in 1948 and its subsequent sale on August 20th of the following year.
To the best of our knowledge the present watch has never before been offered in public.
Production of reference 1579 was launched in 1943. The large case and unusual lugs, also called spider lugs because of their resemblance to a spider's legs, make it easily distinguishable from other Patek Philippe chronograph wristwatches of the era.
A similar model is illustrated in Patek Philippe Wristwatches, by O. Patrizzi, Volume 2, p. 134, pl. 558.
