Description
A circular survivor from a bygone era, this 14K gold pocket watch case back displays the classic hallmarks of German horological history. The piece features a distinct crescent moon and crown stamp, signifying its origin and purity. While the years have lent it a heavy patina and surface oxidation, the structural integrity of the gold remains. It represents a fragment of late 19th-century luxury, likely once housing a precision mechanical movement from a major German or Swiss-German watchmaker.
Key Features
German National 14K Crescent and Crown hallmark; high-digit serial number indicating mass production; visible verdigris (green corrosion) suggesting high copper content in the alloy.
Color & Finish
Pale yellow gold with a dull, matte surface finish due to heavy oxidation and patina. Evidence of historical high-polish that has been clouded by scratches and chemical exposure.
Hallmarks & Stamps
Features a crescent moon and crown hallmark (German Reichsgoldstempel for 14K/585 purity post-1888) and a 6-digit serial number '221106' stamped near the bottom edge.
Dimensions Estimate
Approximately 35mm to 45mm in diameter; standard size for a men's open-face pocket watch or large hunter-case component.
Gemstones & Inlays
None visible on this component; purely metallic construction with mechanical stampings.
Clasp & Closure
Not applicable; originally part of a friction-fit or hinged assembly for a watch case.
Chain & Links
Not applicable; the item is a circular, flat metallic casing component.
Craftsmanship Details
Machine-stamped construction with hand-finished serial numbering. The hallmark was struck with enough force to create a clean, deep indentation, indicating high-quality steel dies.
Authentication Indicators
Hallmark depth and style are consistent with German assay standards. The serial number stamping shows appropriate period-correct serif font. Green spots (verdigris) are a red flag for gold-filled items but can also occur on low-karat solid alloys with high copper.
Origin & Maker
Germany. The 'Moon and Crown' (Reichsgoldstempel) indicates German manufacture or assaying for domestic sale. Maker unidentified (missing maker's mark).
Era & Period
German Late Victorian / Wilhelminian era (circa 1890-1915). Characterized by standardized national hallmarking and industrial watchmaking.
Age Estimate
Produced between 1890 and 1920 based on the style of the German national hallmarks and the font of the serial number.
Cultural Significance
Represents the peak of personal timekeeping as a status symbol before the widespread adoption of the wristwatch during and after World War I.
Condition Notes
Grade: Poor to Fair. Significant surface oxidation, deep scratches, and verdigris spots. The metal appears dull and requires professional restoration to regain its luster.
Value Estimate
Primarily melt value (approx. $180-$350 depending on exact weight) with a slight premium if a collector can match it to a specific missing movement/case.
Care & Maintenance
Gentle cleaning with a soft cloth and mild soap. Avoid harsh chemicals that could react with the copper content. Professional ultrasonic cleaning recommended only if structural integrity is confirmed.

Interesting Facts
The 'Crescent Moon and Crown' hallmark was introduced in Germany in 1888 to unify the various city-state marks (like the Hanseatic marks) into one national standard for gold.
