Jeweled Watch Case / Bracelet Component

Purity

18K (750 fineness) with suspected white gold plating or composition; 75% pure gold alloy content.

Gold Type

White Gold with visible high-polish finish; alloy likely includes nickel or palladium for color.

Weight

Estimated case weight of 8-12 grams excluding movement; substantial side profile suggests a solid rather than hollow build.

Description

A sophisticated white gold cocktail watch case featuring a gracefully curved profile. The bezel is embellished with a row of diamonds that follow the arched contour, while the lug pins are uniquely accented with vibrant blue cabochons. This piece represents the mid-century transition from ornate Art Deco to sleek, streamlined luxury.

Key Features

Curved 'Tank' style silhouette, diamond-set chamfered edges, and distinctive blue cabochon lug fasteners.

Color & Finish

High-polish silver-toned finish with significant surface scratching and oxidation; metallic grey-white luster.

Hallmarks & Stamps

No visible stamps on the side profile; hallmarks would typically be located on the interior back case or lug underside.

Dimensions Estimate

Estimated 25mm-30mm length; approx. 6mm thickness; fits a standard feminine cocktail watch movement.

Gemstones & Inlays

Bezel-set round brilliant diamonds (approx. 0.01-0.02ct each) along the curved edge; two blue synthetic or sapphire cabochons on the strap pins.

Clasp & Closure

Screw-in pin lug system for strap attachment; case appears to be a snap-back or pressure-fit construction.

Chain & Links

Attaches to a black leather or cord strap; lugs are integrated and straight-edged with decorative blue-capped pins.

Craftsmanship Details

Machine-cast main body with hand-set pavé diamonds and hand-finished lug pin caps; precise symmetry in the arched bezel curvature.

Authentication Indicators

Color uniformity across the scratch indicates solid white gold rather than plating; stone setting style is consistent with mid-century hand-finishing.

Origin & Maker

Likely European origin (Swiss or Italian); design language is consistent with luxury houses such as Omega or Longines.

Era & Period

Late Retro to Mid-Century Modern (1940s-1960s) styling; common in high-end dress watches of that era.

Age Estimate

Circa 1950-1965 based on the case thickness and the use of cabochon-topped pins for the lugs.

Cultural Significance

Cocktail watches were essential status symbols for women in mid-century formal society, designed to function as jewelry first and timekeepers second.

Condition Notes

Fair-Good condition. Significant surface micro-scratches and one deep gouge/abrasion on the lateral side. Stone settings appear secure but need cleaning.

Value Estimate

Melt value estimated at $450-$600; collectible/retail value as a complete vintage watch could range from $1,200 to $2,500 depending on brand.

Care & Maintenance

Requires professional ultrasonic cleaning; white gold may require rhodium replating to restore the bright mirror finish once polished.
