Object description

Dial Configuration and Display

The timepiece features a regulator-style dial layout executed with a vertical satin-brushed silvered dial finish. The display divides time indications across separate axes: minutes are shown via a central blued-steel hand, while hours and running seconds are positioned on dedicated subsidiary dials at 12 and 6 o'clock, respectively. A date aperture is integrated within the lower subdial at 6 o'clock.

Calendar functions are completed by beveled apertures for the day of the week at approximately 10 o'clock and the month at 2 o'clock. The dial is printed with the 'PATEK PHILIPPE GENEVE' signature at 3 o'clock. The seller description separately characterizes the dial as brushed anthracite with rose gold rings on the subdials.

  • “The super chic brushed anthracite dial is highlighted with delicate rose gold rings on the subdials”

Case and External Construction

The watch features a polished 18K white gold case measuring 40.5 mm in diameter, constructed with sharp angled lugs and a fluted winding crown. The catalog description asserts that the case design draws on the architecture of reference 3448 with sharp lugs and bezel.

The strap is fitted with an 18K white gold 'Art Deco' pin buckle. The seller reports the example to be in 'never polished' condition, though this assessment represents seller commentary that is not independently verifiable from the available frontal record.

Evidence for this section
  • “Diameter 40.5mm”
  • “Metal 18K White Gold”
  • “Polished white gold case with sharp angled lugs and fluted winding crown”
  • “Clasp/Buckle White Gold 'Art Deco' Pin Buckle”

  • “Found in superb, 'never polished' condition”

Calibre Details and Documented Accessories

According to the source documentation, the watch is powered by the self-winding Calibre 31-260. The catalog notes the reference as Patek Philippe's first production model to incorporate both Spiromax and Pulsomax escapement innovations. However, the movement and case back are not visible in the provided image.

Dated to 2019, the watch is listed as accompanied by its original Patek inner and outer box, certificate, wallet, instructions, cloth, and setting stylus. Individual case and movement serial numbers are not disclosed in the source entry.

Evidence for this section
  • “Calibre Self-winding (automatic) Cal. 31-260”
  • “the first production watch to host the advanced research escapement innovations, Spiromax and Pulsomax together.”
  • “Year 2019”
  • “Accompanied by Original Patek Inner and Outer Box, Certificate, Wallet, Instructions, Cloth and Stylus”

Open research questions

  • What specific case and movement serial numbers are inscribed on the physical timepiece and its certificate?
  • Why does the seller text describe an 'anthracite dial with rose gold rings' while the direct observation and model standard indicate a vertical satin-brushed silvered dial with blued hands?
  • What exact date and authorized retailer are recorded on the original certificate of origin?
