Omega 19-Ligne Open-Face Pocket Watch

Partially verified

This antique open-face pocket watch by Omega features a Lépine-style base-metal case housing an Omega 19-ligne bar caliber (19''' LOB) with stem-wind and stem-set mechanisms. Dated by the source to circa 1900–1902 based on its 7-digit serial sequence, it is reported to feature an in-house non-precious case with an internal Globe/Goddess stamp. The white dial displays Arabic numerals, an outer minute track with five-minute markers, and a subsidiary seconds subdial at 6 o'clock. The watch weighs 106.3 grams excluding the accompanying 33 cm antique curb link chain, which is fitted with a swivel dog-lead clasp and a large spring ring.

Object description

Dial and Visual Presentation

Direct visual inspection shows a white dial featuring black Arabic numeral hour markers and a subsidiary seconds dial at the 6 o'clock position. The hands include ornate openwork rose-gold-toned hands indicating the hours and minutes alongside a straight hand for the subdial seconds.

The open-face configuration displays the winding crown and bow positioned at 12 o'clock. A curb link pocket watch chain is shown attached to the bow via a large spring ring.

Evidence for this section
  • “White dial with black Arabic numeral hour markers and a subsidiary seconds dial at 6 o'clock”
  • “Ornate openwork rose-gold-toned hands and a straight subdial seconds hand”
  • “Crown and bow positioned at 12 o'clock attached to a curb link chain via a large spring ring”

Reported Movement and Internal Markings

The seller listing reports that the watch houses an Omega 19-Ligne Open-Face Bar Caliber (19''' LOB). This movement is described by the source as featuring a matte gilt-frosting finish, manual stem-wind and stem-set mechanisms, and traditional regulator markings reading '(F/A, S/R)'.

A production era of circa 1900–1902 is asserted based on a reported 7-digit case serial number sequence in the 1.7-million range (1,762,207). The source also reports that the interior of the case back bears an antique Omega factory 'Globe/Goddess' stamp indicating an in-house Swiss-manufactured non-precious case.

Evidence for this section
  • “Movement / Caliber: Omega 19-Ligne Open-Face Bar Caliber (19''' LOB). Featuring a matte gilt-frosting finish, manual stem-wind, stem-set mechanism, and traditional regulator markings (F/A, S/R).”
  • “Era / Production Period: Circa 1900–1902 (Verified by the 7-digit case serial number sequence in the 1.7-million range).”
  • “Includes the official antique Omega factory "Globe/Goddess" stamp inside the case back, indicating an in-house Swiss-manufactured non-precious case.”

Case Specifications, Accessories, and Verification Limits

The case is listed as an open-face (Lépine style) configuration, with an approximate diameter between 47mm and 51mm measured horizontally excluding the winding crown. The total weight of the watch head alone is reported as 106.3 grams. The source notes nickel plating wear on the outer metal case that reveals hints of underlying base metal.

The watch is accompanied by a matching antique base-metal curb link chain measuring 33 cm in total length, described as a Single Albert style with a swivel dog-lead clasp and an anchoring spring ring. Because the provided visual record consists solely of a front dial-side photograph, internal components such as the movement caliber, case stamps, and serial numbers are not visible and rely on source description.

Evidence for this section
  • “Size / Diameter: approximately 47mm to 51mm (measured horizontally from left to right, strictly excluding the winding crown)”
  • “Total weight: 106.3 grams (watch head only).”
  • “Accompanied by a heavy-gauge, matching antique base-metal curb link chain measuring 33 cm in total length (Single Albert style, featuring an authentic swivel dog-lead clasp and a large anchoring spring ring).”

Open research questions

  • What is the exact caliper-measured diameter and thickness of the pocket watch case?
  • Can physical examination of the uncased movement confirm the 19''' LOB caliber designation and serial number matching 1,762,207?
  • Does direct inspection of the case interior verify the presence of the Omega 'Globe/Goddess' trademark stamp?
