Description
A well-worn vintage open-face pocket watch featuring a snap-back case. The item displays a utilitarian aesthetic with a simple knurled crown and a replacement silver-toned bow. The surface shows extensive wear, suggesting a lifetime of use in a pocket without a protective fob.
Key Features
Replacement silver-toned bow, knurled winding crown at the 12 o'clock position (typical for open face), and tiered case back design.
Color & Finish
Dull, mustard yellow with significant brown and greenish oxidation (verdigris). Texture is matte due to heavy surface corrosion and micro-scratching.
Hallmarks & Stamps
No hallmarks visible on the external case back. Likely located on the internal dust cover or case back interior (e.g., 'Guaranteed 20 Years' or 'Carlyle').
Dimensions Estimate
Case diameter approximately 45mm to 50mm (Men's size 16s or 12s standard).
Gemstones & Inlays
None visible. Plain metal construction.
Clasp & Closure
Friction-fit snap back case with a standard circular bow (loop) for a chain attachment.
Chain & Links
Not applicable; features a steel or base-metal bow at top. Edge has a flat, rounded profile consistent with early 20th-century utility watches.
Craftsmanship Details
Mass-produced stamped metal case. Soldering is visible at the pendant neck. Functional but lacks high-end horological finishing.
Authentication Indicators
Red flags for solid gold: The presence of greenish/brown oxidation and uneven color wear (brassing) confirm this is not solid gold but a base metal alloy.
Origin & Maker
Likely American or Swiss origin; common case makers of this era include Keystone, Wadsworth, or Star Case Co.
Era & Period
Early to Mid-20th Century (circa 1920-1950). Design reflects utilitarian Art Deco or post-Depression era minimalism.
Age Estimate
Approximately 75-100 years old based on the crown style and bow construction.
Cultural Significance
Pocket watches were the primary timekeeping tool for men until the widespread adoption of wristwatches after World War I, signifying punctuality and social status.
Condition Notes
Fair to Poor. Significant 'brassing' (wear-through of plating to the base metal), surface pitting, and oxidation. The bow does not match the case color, indicating a repair.
Value Estimate
Minimal ($10 - $30 USD). Value is primarily in the internal movement (if functional) rather than the metal content, as this is not solid gold.
Care & Maintenance
Do not use abrasive cleaners. Wipe with a soft cloth. Keep away from moisture to prevent further oxidation of the base metal.

Interesting Facts
During the early 20th century, gold-filled cases were 'guaranteed' to last a certain number of years (10, 20, or 25) before the gold layer would wear through to the brass below.
