This Patek Philippe & Cie keyless pocket watch, identified by movement number 808579 and case number 410124, was produced in the 1920s. The watch features an 18K yellow gold four-body, "demi-bassine" polished case, which includes a hinged gold cuvette.

Time is displayed via yellow gold Breguet-style hands. Internally, the watch is powered by a 38 mm (17''') nickel caliber movement.

Signatures and Grading
The components of the watch—the dial, the case, and the movement—are each signed by Patek, Philippe & Cie. These markings confirm the consistency of the components as original to the assembly. The auction house has provided a condition report based on their internal grading system. The case is assigned a grade of 3, while the movement is graded as 3-6 and the dial as 3-5-01.
Movement and Escapement
The timepiece is powered by a 38 mm (17''') nickel caliber movement. The plates and bridges are decorated with "fausses côtes," and the assembly contains 18 jewels. The timekeeping is regulated by a straight-line counterpoised lever escapement, paired with a cut bimetallic compensation balance. The balance assembly is adjusted to 8 positions for precision, utilizing a blued steel Breguet balance-spring to maintain accuracy.
Case and Dial Construction
The watch is housed in an 18K yellow gold, four-body, "demi-bassine" case that is fully polished. The case design incorporates a hinged gold cuvette to protect the movement. The dial is presented in a two-tone silver finish, providing a layered visual aesthetic. Applied yellow gold Arabic numerals are used at the main hour positions, while painted indexes define the remaining markers. An outer minute track frames the dial, and a small subsidiary seconds dial is located at the 6 o'clock position, featuring a guilloche pattern. The time is read through yellow gold Breguet-style hands.
