The subject item is best identified as Omega Seamaster Automatic with Tapestry Dial, c.1966, Mid-1960s, Omega SA, Bienne, Switzerland. During the 1960s, Omega reached a golden era of mechanical watchmaking, deploying legendary robust in-house movements like the Caliber 562 and 565. The Omega Seamaster, launched in 1948, evolved into the premier waterproof gentleman's watch of the mid-20th century, aggressively rivaling Rolex in precision and style. The rare 'Tapestry' or 'Ribbon' dial—featuring subtle vertical striations—elevated the Seamaster from a rugged tool watch to a high-fashion accessory by dynamically catching the light. In the mid-1960s, a gentleman was expected to transition seamlessly from sporting activities to formal evening wear; sophisticated waterproof watches like this filled that dual-purpose role perfectly.^[1]

Valuation is anchored by the presence of the special-order 'Tapestry' dial, which historically commands a 30% to 50% premium over equivalent flat or sunburst silver-tone dials. Direct comparables establish a firm auction floor: a 1963 gold-tone metal (untested)-filled Tapestry model in unserviced estate condition hammered at $550 (Cordier Auctions, 2025). Conversely, verified dealer sales for serviced, stainless steel equivalents reach approximately $890. While top-tier vintage dealers retail fully serviced, pristine examples on original 'Beads of Rice' bracelets for $1,500 to $2,300, the peer-to-peer and auction fair market value for a 'watch-only' example with unknown service history appropriately sits in the $650–$950 range. If the unidentified case material is determined to be solid 14k or gold-tone metal (untested) rather than gold-tone-capped or steel, this range would shift significantly upward.^[1]
