NEW available at my boutique is this superb:

Patek Philippe Deck Watch, Observatory Certificate

Case 600734, movement 178455

Manufactured 1921, Sold 1938, Gilded movement

Beyer Certificates, Patek Philippe letter and extract from archives

Gilt “extra quality” lever chronometer movement with two Geneva seals, Guillaume balance with gold and platinum poising and regulator screws, diamond end stone, blued steel hairspring with overcoil, swan neck regulator, all engravings and polishing are hand finished to the highest standard.

Massive silver dial with “grainé” finish and hand engraved and enameled inscriptions, roman numerals, Up/down indicator (36) at “12” and oversized small seconds and outer minute track, Patek Philippe signature with movement number.

Fine open face sterling silver case with 0,900 Swiss hallmark, silver dome with engraved movement number, bow with PPC stamp.

What makes this example as well very special is that the movement is gilt finished combined with the silver case, as confirmed by the two Beyer certificates. I haven’t seen such a combination yet.

This timepiece is accompanied by the following five documents, which makes it more special and confirms its originality and history:

  1. .
    Patek Philippe Extrait des Archives which quotes: “Geneva Observatory Timing Contests: 1st class test result in chronometer performance and honorable mention, manufactured in 1921 and sold in 1938.
  2. Observatory timing Certificate which quotes “mention honorable”, Régleur C. Batifolier.
  3. Patek Philippe letter to Beyer Chronométrie from 1987 confirming the originality.
  4. Beyer certificate dated 1994, confirming the originality of the watch and that the movement had been serviced at the Beyer atelier
  5. Beyer certificate after 2017, confirming the Patek letter from 1987, the Beyer certificate from 1994, the Patek extract from 2017, the originality of the watch and that the movement had been serviced at the Beyer atelier

This Patek Philippe Deck watch is certainly a great addition to every high-class collection, due to its uniqueness, quality and documented history.
