Object description

Dial and Visual Display

The pocket watch displays a white enamel dial with black Arabic hour numerals, an outer perimeter track graduated to fifths of a second, and a subsidiary seconds dial positioned at 6 o'clock. In the listing photograph, the dial is fitted with blued steel spade hour and minute hands and a long central chronograph hand. It is signed "New York Standard Watch Co, USA".

The dial is covered by a mineral glass. The seller evaluates the dial as "85% mint condition", noting "two forked hairlines - on the 8 and sub seconds".

Case Construction and Exterior

The piece is housed in an open-face Sterling silver case reported as measuring 50 mm by 20 mm. The case features a screw-off back, a hinged bezel, coin-edged sides, and engine turning. At the 12 o'clock position, a fluted crown with an integral chronograph button is set within a silver bow, while a visible bezel hinge is situated at 6 o'clock.

The seller describes the case condition as "90% mint condition", reporting "a small ding on the bezel and light scratches on the back but apart from that a very clean and crisp case". The reverse side is not pictured in the listing photograph.

Reported Movement and Operating Condition

Because the case back is not opened in the catalogue image, all movement details derive from the listing text. The seller catalogues the movement as an 18-size, 7-jewel stem-wound and lever-set mechanism built on a nickel three-quarter plate layout with a lever escapement and exposed steelwork for the chronograph mechanism. The movement is inscribed "New York Standard Watch Co, Pat Mar 22 04, 5536235".

The watch is offered as non-functional within the dealer's restoration section and without warranty. The seller notes that while it "has a good balance and spring", it is "fully wound and not working", with the movement rated at "85% mint condition – several light scratches".

Evidence for this section
  • “18s 7J chronograph by New York Standard Watch Co c1908”
  • “nickel ¾ plate movement has a lever escapement and has exposed steel work for the chronograph function”
  • “signed “New York Standard Watch Co, Pat Mar 22 04, 5536235””
  • “stem wound / lever set”
  • “This watch is sold in our Watches for restoration section and does not come with a warranty”
  • “The watch has a good balance and spring but is fully wound and not working”

Open research questions

  • What specific mechanical obstruction prevents the movement from running while fully wound despite an intact balance and spring?
  • What silver purity hallmarks or maker marks are stamped inside the screw-off back of the case?
  • To which United States patent does the plate inscription 'Pat Mar 22 04' correspond?
