Patek Philippe Reference 1433J, manufactured circa 1939–1946, in 18K yellow gold.
Silvered opaline dial with raised "Patek Philippe & Co." long signature. Roman numerals at 12, 3, and 9 are complemented by applied baton markers at the remaining hours. The dial omits a peripheral minute track, leaving the surface largely uninterrupted. A subsidiary seconds register is positioned at 6 o'clock.
The yellow gold case exhibits proportions typical of smaller Calatrava-era wristwatches of the late 1930s and early 1940s. The case interior bears stamp 620-471 and retains period hallmarks consistent with Geneva manufacture during the era.
Manually wound calibre 9-90.
Condition: The watch presents in well-preserved vintage condition, showing honest surface wear consistent with age and careful stewardship. The dial retains the balanced appearance characteristic of period silvered opaline examples.
