Object description

Dial and Retailer Attribution

The open-face pocket watch features a white dial with black Arabic numerals and an outer railway minute track. Time is indicated by blued steel hands with circular aperture accents, accompanied by a subsidiary seconds dial at 6 o'clock.

The dial is marked with retailer identification across three lines: 'WINEGARTENS / 145, Bishopsgate / LONDON E.C. 2', with 'SWISS MADE' positioned at the bottom rim. According to the seller's description, the enclosed movement is also signed by Winegartens, a London-based jeweller and retailer.

Case Construction

The watch is housed in an open-face case measuring 50 mm in diameter, excluding the winding stem and suspension bow. Visible features include a top bow, a fluted winding crown, and a glass lens.

The seller identifies the case as the gold-plated 'Star' model produced by Birmingham case maker Aaron Dennison. The movement inside is noted by the seller as being protected by an inner hinged cover.

Reported Movement and Dating Limitations

The movement is described by the dealer as a 15-jewel stem-winding Cortébert calibre 536 supplied to Winegartens as a private-label piece. Because the movement is not visible in the primary photograph and is housed behind an inner cover, these mechanical specifications rely solely on dealer documentation.

The listing dates the watch to the 1930s. No movement serial numbers, case serial numbers, or production records are provided in the source to independently verify this manufacture date.

Evidence for this section
  • “The watch has a 15-jewel stem-winding movement which is working nicely.”
  • “This is a Cortebert calibre 536 movement, supplied to Winegartens to be sold as a private label piece.”
  • “The Vintage Wrist Watch Company has dated this Vintage Gold Pocket Watch to the 1930s.”

Open research questions

  • What serial or model reference numbers are stamped inside the Dennison Star case back and inner hinged cover?
  • Does the movement bear Cortébert caliber stamps or a serial number beneath the Winegartens signature to substantiate the 1930s dating?
