Description
A stunning example of mid-century Swiss horology and jewelry design. This Omega Ladymatic features a petite 18K yellow gold case seamlessly integrated into a luxurious, supple brick-link gold bracelet. Its radiant yellow tone and iconic dial aesthetic make it both a precise timepiece and a high-end vintage accessory.
Key Features
The 'Ladymatic' script on the dial representing one of the smallest automatic movements ever made; the high-relief applied gold hour markers; the seamless integration between the case lugs and the fluid bracelet links.
Color & Finish
High-polish mirror finish on the rounded links with a warm, buttery yellow color. Visible surface patina and minor micro-scratches consistent with long-term wear.
Hallmarks & Stamps
Usually found on the interior of the case back and the clasp. Expected marks include '750' in a diamond or rectangle, the Helvetia head (Swiss hallmark for 18K), and the Omega logo with a reference number.
Dimensions Estimate
Case diameter: 18mm-22mm (petite lady's size); Bracelet width: 10mm-12mm; Length: approximately 6.5 to 7.0 inches.
Gemstones & Inlays
None visible on the bracelet or case; the dial features applied gold arrow markers and Arabic numerals at 12 o'clock.
Clasp & Closure
Integrated fold-over box clasp, typically featuring a safety catch and an embossed Omega logo on the exterior for security and branding consistency.
Chain & Links
Three-row 'Brick' or 'Beads of Rice' hybrid link construction. The links are articulating and hand-assembled with pins, providing high flexibility and a fabric-like drape on the wrist.
Craftsmanship Details
Exceptional Swiss construction; the links are individually articulated for maximum comfort. The case bezel is pressure-fitted with high-precision tolerances, and the dial features high-quality hand-applied indices.
Authentication Indicators
The crispness of the 'OMEGA' logo on the dial, the specific 'arrowhead' style markers, and the weight-to-volume ratio of the heavy gold bracelet links which are difficult to replicate in plated base metal.
Origin & Maker
Switzerland; manufactured by Omega SA. Omega is renowned for precision movements and high-quality jewelry-grade watch cases from this era.
Era & Period
Mid-Century Modern (circa 1950s-1960s). This is indicated by the 'Ladymatic' branding and the distinct geometric yet soft link style popular in post-war Swiss design.
Age Estimate
Circa 1955-1965. The dial font and the Ladymatic movement (first launched in 1955) place it firmly in this decade.
Cultural Significance
Represents the 1950s shift toward 'functional jewelry' for women, where the watch became a status symbol of independence and elegance in the professional and social spheres.
Condition Notes
Good to Very Good. The gold shows soft wear and rounded edges from decades of use. The dial shows minor spotting (oxidation) characteristic of vintage watches. The links appear tight with minimal stretch.
Value Estimate
Market Value: $2,500 - $4,500 USD. Value is split between the gold melt value (approx. $1,500-$1,800) and a significant collector's premium for the Omega brand and the specific Ladymatic model.
Care & Maintenance
Avoid ultrasonic cleaners as they can damage vintage movements. Clean the gold bracelet with a soft cloth and mild soap. Keep away from perfumes and hairsprays which can tarnish the gold alloy and damage gaskets.
