Vintage Westclox Open-Face Pocket Watch

Partially verified

This is an open-face pocket watch produced by Westclox in the United States, attributed by the source to the mid-20th century. The timepiece houses a manual-winding movement stamped 'MADE IN U.S.A.', featuring blued screws, a visible balance assembly, and an index regulator marked with 'F' and 'S'. The source reports a 49.7 mm round chrome-plated metal case fitted with an acrylic crystal and a snap-on press-fit case back. The listing also describes a dark green dial with Arabic numerals, though only the movement and the removed case back are visible in this view.

Object description

Visible Movement and Mechanical Features

Direct visual inspection of the movement reveals plates secured by blued screws, with the balance wheel assembly visible near the rim. Adjacent to the balance wheel, a curved regulator index is marked with 'F' and 'S' to indicate fast and slow regulation.

The movement plate is visibly stamped 'MADE IN U.S.A.', which aligns with the seller's claim of United States manufacture. A crown and bow assembly is positioned at the 12 o'clock relative orientation of the movement. No caliber identification is inscribed on the visible plate surface or reported in the source.

Evidence for this section
  • “The exposed movement plate is stamped 'MADE IN U.S.A.' and secured with blued screws.”
  • “A regulator scale marked 'F' and 'S' is visible adjacent to the balance wheel.”
  • “The crown and bow are positioned at the 12 o'clock relative orientation of the movement.”

Case Construction and Observed Housing

The watch is housed in an open-face, round chrome-plated metal case. According to the seller's specifications, the case size measures 49.7 mm, extending to 54 mm including the crown, with an overall thickness of 14 mm.

The circular press-fit case back is shown detached beside the case in the primary image. The seller states that the watch is fitted with an acrylic crystal and a fixed bezel, though neither is directly observable from the rear view.

Evidence for this section
  • “Case Material: Chrome-plated metal”
  • “Case Size: 49.7”
  • “Case Diameter w/Crown: 54”
  • “The detached circular press-fit case back sits beside the case.”

Reported Dial Features and Verification Limits

The retailer describes the front of the pocket watch as featuring a dark green analog dial with Arabic numerals arranged in a raised outer chapter ring and a central minutes track. The hands are described as gold-tone, and the dial is reported to be signed 'WESTCLOX' and 'MADE IN U.S.A.' at the bottom edge.

Because the provided visual record only displays the rear of the movement and the removed case back, the described dial color, layout, and hands cannot be confirmed from this view. Furthermore, the mid-20th-century dating is an estimated era provided by the seller rather than a date determined by a visible or recorded serial number.

Evidence for this section
  • “The watch features a dark green dial with Arabic numerals in a raised outer chapter ring and a central minutes track.”
  • “The hands are gold-tone, with a thick hour hand and broader minute hand.”
  • “The dial is signed “WESTCLOX” and “MADE IN U.S.A.” at the bottom.”
  • “Year / Era: Mid-20th Century – Vintage”

Open research questions

  • What specific Westclox movement caliber or model family corresponds to this plate architecture and balance wheel layout?
  • Does direct visual inspection of the dial face confirm the reported dark green finish, raised chapter ring, and dial signatures?
  • Are there any internal date stamps, patent dates, or factory markings inside the case back or on the reverse of the dial to refine the mid-20th-century dating?
