Patek PhilippeThis open-face keyless-winding pocket chronometer in 18k pink gold is signed by Patek Philippe and dates to circa 1880. With a 53 mm diameter case, it features a white enamel dial with Roman numerals, an outer minute track with Arabic five-minute numerals, and a subsidiary seconds dial at 6 o'clock.
According to the auction source, the 21''' gilded brass movement is based on an ébauche likely produced by Ambroise Duret of Geneva. It incorporates a going barrel, straight-line moustache lever escapement, compensated crank balance, and a blued steel free-sprung cylindrical hairspring with terminal curves.

- Dial and Case Presentation
- The pocket chronometer features an open-face 18k pink gold case measuring 53 mm in diameter, with a fluted crown and hinged bow positioned at 12 o'clock. The white enamel dial is executed with suspended Roman numerals and blued steel spade hands. A subsidiary seconds display is located at 6 o'clock with Arabic ten-second numerals and a blued steel hand. The dial is signed 'Patek Philippe & Cie Genève' below the 12 o'clock position.
- Attribution and Archival Status
- The auction catalog assigns the piece a date of circa 1880 and records signatures across the dial, case, and movement. The ébauche source is not definitively established in the record, which states 'ebauche probably by Ambroise Duret, Geneva'. The catalog explicitly notes that an extract from the Patek Philippe archives is not available because the watch does not match their information, leaving manufacture documentation unresolved in the provided record.
- Movement Architecture and Regulating Organ
- The movement is recorded by the catalog as a 21''' gilded brass caliber with a going barrel and gold screwed-chaton settings. The escapement is cataloged as a straight-line equilibrated lever escapement, noted in the description as 'a moustache'. The regulating organ is described by the auction house as a compensated crank balance with offset arms, fitted with gold and platinum poising screws and a blued steel free-sprung cylindrical hairspring with terminal curves. Both the movement and case are listed with number 47756.

- Research required: The ébauche maker attribution to Ambroise Duret is described by the catalog as probable rather than confirmed.
