Introduced in 1932, the Patek Philippe Calatrava ref. 96 established a design language that would become one of the most enduring in Swiss watchmaking. Its restrained proportions, clean dial and elegantly constructed case reflected a philosophy in which simplicity and precision were paramount. By the late 1940s, the manufacture was beginning to develop the next generation of Calatrava references, introducing subtle technical refinements whilst preserving the understated character of the original. Among these was the ref. 2457, introduced around 1950 as a successor to the celebrated ref. 96. Retaining the familiar 31.5mm case, the new reference incorporated a centre seconds movement, providing a more contemporary interpretation of Patek Philippe's classic dress watch. Although the Calatrava was predominantly produced in precious metals, stainless steel examples are particularly interesting, reflecting a period when steel remained an uncommon choice for the manufacture's elegant time-only wristwatches.

This particular ref. 2457 was manufactured in 1950 and sold on 17 April 1951, as confirmed by its accompanying Patek Philippe Extract from the Archives. Its stainless steel case is complemented by a silvered dial featuring beautifully faceted white gold hour markers, with a distinctive double marker at twelve o'clock. The dauphine hands are accompanied by a slender blued centre seconds hand, providing a subtle contrast against the monochromatic dial. A finely printed outer seconds track adds a further element of precision to the otherwise minimalist design. The watch is powered by Patek Philippe's manually wound calibre 27 SC, an important centre seconds movement used during this period. Particularly noteworthy is the presence of both reference numbers, 96 and 2457, stamped inside the case back, an unusual detail that illustrates the transition between these two important Calatrava references.

Watch is in overall near-mint condition. The stainless steel case shows light surface scratches and marks, with razor sharp edges and surfaces. The case back shows minor scratches. Caseback is signed both ref. 96 and 2457, making it a part of the very first batch of 2457s, lightly made from left over 96 components. The silver dial exhibits some light surface marks, including a scratch on the lower left side. The applied white gold hour markers show some marks, while the hands remain reasonably clean. It is fitted with a Patek Philippe leather strap and stainless steel pin buckle. Comes with a Patek Philippe Extract from the Archives, which confirms the fitted dial.

Please Note: Due to CITES considerations, if the watch is to be shipped outside of the USA, the exotic skin strap will have to be removed.
