Patek PhilippeThis Patek Philippe display clock, identified by the model name 'L'Ora', dates to circa 1930. The object is a manual wind, deck-style lever chronometer housed within a 90 mm chrome-plated metal case.
Its internal mechanism is a gilt brass movement featuring 21 jewels, the Geneva hallmark, and wolf's tooth winding. The chronometer is equipped with a straight-line calibrated lever escapement and an anibal-brass Guillaume balance paired with a special alloy Breguet balance spring. Precision regulation is managed via a swan-neck micrometric regulator. The auction description notes a stop feature is located at the 4 o'clock position.
The clock face bears the Patek Philippe & Co. Geneve signature. While the overall condition is noted as excellent, the auction house reports minor oxidation on the case, movement, and dial, and recommends a technical overhaul for the movement.

- Movement and Escapement
- The internal mechanism is a manual wind, gilt brass movement with 21 jewels. It is equipped with a straight-line calibrated lever escapement and features the Geneva hallmark, indicating the movement's adherence to specific regional standards. The timekeeping regulation is performed via a swan-neck micrometric regulator, designed for precise adjustment. A key feature of the escapement is the anibal-brass Guillaume balance, coupled with a special alloy Breguet balance spring featuring inner and outer terminal curves. The movement is constructed with wolf's tooth winding.
- Signatures and Condition
- Patek Philippe is identified as the manufacturer of the dial, case, and movement. The movement carries the serial number 191446, while the case is numbered 610487. The authenticity of the signatures is confirmed by their presence on the dial, the exterior case hardware, and the internal movement plate. Regarding the physical state of the clock, the auction house assigned a grading of 'AAA Excellent'. Despite this grade, specific observations note that the case, dial, and movement exhibit slight oxidation. These findings, combined with the explicit recommendation for an overhaul, define the current technical state of this vintage horological instrument.
