Description
A genuine vintage Omega pocket watch case back in solid 14K yellow gold. The interior displays the signature Omega hallmark and Swiss origin stamps that collectors look for to verify authenticity. The hand-engraved service marks suggest a history of professional maintenance, common in high-end Swiss timepieces of the mid-20th century.
Key Features
Deep-struck Omega factory logo, unique 7-digit serial number, and hand-etched watchmaker service codes indicating a long functional life.
Color & Finish
Classic warm yellow gold with a high-polish interior finish. The surface shows a significant network of micro-scratches and heavy circular scuffs (swirls) from decades of handling.
Hallmarks & Stamps
Prominent Omega 'Greek Letter' logo inside a circular frame; 'Omega Watch Co. FAB. SUISSE' (Swiss Made); Case serial number '8363014'; Hand-scratched jeweler's service mark 'K 118209'.
Dimensions Estimate
Approximately 45-50mm in diameter (Size 12 or 16 pocket watch standard).
Gemstones & Inlays
None visible on the case interior; typical for this functional horological component.
Clasp & Closure
Hinged 'snap-back' closure. The hinge appears intact at the bottom of the frame, designed for a friction-fit seal to protect the movement.
Chain & Links
Not applicable; this is a case component. The case edge appears smooth and rounded (basine style).
Craftsmanship Details
Machine-stamped with high-pressure dies for the hallmarks; the case itself is likely forged and turned on a lathe for a precision fit with the bezel.
Authentication Indicators
The 'FAB. SUISSE' stamp is consistent with Omega's marking conventions for the French-speaking market and international exports. The serif font used for the serial number matches known 1930s factory dies.
Origin & Maker
Switzerland; manufactured by Omega Watch Co., Bienne. Omega is world-renowned for precision and was a primary supplier of chronometers.
Era & Period
Mid-Century Modern / Late Art Deco transition (1930s-1940s). The typography of the serial number and the logo style are consistent with this period.
Age Estimate
Circa 1934-1939. The 8-million series serial number for Omega watch cases typically correlates to the late 1930s.
Cultural Significance
Pocket watches were the primary status symbol for men before the widespread adoption of wristwatches after WWI; a gold Omega represented the pinnacle of middle-to-upper class engineering and luxury.
Condition Notes
Good / Fair. The metal shows heavy surface wear (fine scratches/swirls) and some minor tarnish or oxidation near the hinge. No major dents or deep gouges are visible in the center.
Value Estimate
Primarily valued for its 14K gold melt weight (approx. $800-$1,200 depending on final weight) plus a 20-30% premium for the Omega brand and vintage horological value.
Care & Maintenance
Avoid chemical dips; use a dedicated gold polishing cloth for the interior. If the movement is still inside, avoid ultrasonic cleaners which can destroy the mechanical lubrication.
