Yellow Gold color on Base Metal (Brass/Steel)
Weight
1.5 - 3.0 grams
Description
This is a stamped metal movement ring, designed to provide a secure fit for a mechanical watch movement within a larger case. While it features a yellow gold-colored finish, the uneven surface degradation and purple-tinted oxidation spots strongly indicate a thin gold plating over a non-precious base metal, likely brass or steel. It features an integrated tab with a hole for a securing screw or stem alignment.
Key Features
Circular gasket shape with extended securing tabs and a singular mounting hole
Color & Finish
Dull yellow gold with significant surface oxidation, tarnish spots, and uneven patina
Hallmarks & Stamps
No visible hallmarks or purity stamps; typical of internal functional components
Dimensions Estimate
Approximately 25mm-30mm diameter; thickness less than 1mm
Gemstones & Inlays
None
Clasp & Closure
Not applicable; friction-fit or screw-secured internal tabs
Chain & Links
Not applicable; stamped flat metal construction
Craftsmanship Details
Industrial die-stamped sheet metal with secondary plating process; lacks the refinement of jewelry-grade hand-finishing.
Authentication Indicators
Red flags for solid gold include the 'purplish' spotting and green-tinged oxidation, which indicate base metal reacting with the environment through a thin layer of plating.
Origin & Maker
Generic Swiss or Asian watch component manufacturer
Era & Period
Mid-Century Modern (1950s-1970s)
Age Estimate
Circa 1960-1980
Cultural Significance
Represents the mass-production era of mechanical horology where functional internal parts were often plated for aesthetics or corrosion resistance.
Condition Notes
Fair to Poor; significant surface corrosion, loss of plating, and visible spotting
Value Estimate
Minimal; primarily functional as a spare part or scrap metal. No significant gold value.
Care & Maintenance
Keep dry to prevent further corrosion of the base metal; do not use abrasive cleaners as they will strip the remaining thin gold layer.

Interesting Facts
Movement rings are essential in horology to adapt standardized movements into various case sizes, ensuring the watch remains shock-resistant.
