Launched in 1941 and remaining in production until the early 1950s, it is one of the rare Patek Philippe watches of the era made predominantly in steel, which could be explained by the fact that it was in production during the Second World War and its difficult aftermath, where gold was reserved for the most complicated watches.

A perfectly timeless watch with a touch of class thanks to its teardrop-shaped lugs, the current reference 1503 features a silvered dial with applied Arabic numerals. The stainless steel case is preserved in excellent condition with well-defined teardrop-shaped lugs.
