Craftsmanship Details
Precision-turned and polished; likely die-struck then finished by hand to ensure a water-resistant snap fit
Authentication Indicators
The color saturation is indicative of high gold content; the 'brassing' absence at wear points suggests solid gold rather than plating

Mid-Century Modern (Late 1940s to 1960s stylistic markers)
Age Estimate
Circa 1950-1965 based on the case shape and crown style
Cultural Significance
Represents the 'Golden Age' of mechanical watchmaking where the gold watch was the ultimate retirement or milestone gift
Condition Notes
Very Good (structural integrity is excellent, though surface shows scratches consistent with daily wear; no major dents)
Value Estimate
Melt value approximately $250-$400 for the gold; significantly higher if part of a complete, working luxury timepiece
Care & Maintenance
Clean with a soft microfiber cloth; avoid ultrasonic cleaners if the movement is still inside; professional buffing can restore mirror finish
