The subject item is best identified as Omega Constellation 'Pie-Pan' Ref. 168.005, c.1963, Early 1960s Mid-Century Modern, Omega Watch Co., Bienne, Switzerland. Mid-century Omega represents the pinnacle of the brand's 'golden era' precision engineering, dominating chronometer production out of Bienne, Switzerland. The Constellation line was launched in 1952 to commemorate Omega's centennial and its unprecedented success at the Geneva Observatory chronometry trials. The architectural 12-sided 'pie-pan' dial is a bold, three-dimensional statement designed to catch light, complemented by the sharp geometry of Gérald Genta's 'dog-leg' lugs. Produced circa 1963, this reference embodies the apex of Mid-Century Modern design, merging robust Swiss sports-watch engineering with formal dress elegance.

Valuation is securely locked to the exact configuration: Omega Ref. 168.005 in stainless steel with a pie-pan dial. Direct comparable sales dictate a sharp divide between fully serviced retail models and unserviced private-sale examples. A baseline of $1,400 is firmly established by equivalent unserviced, watch-only sales at Christie's and OmegaForums. Freshly serviced private sales push toward $1,950, while fully sorted examples from premium dealers like Hodinkee command $2,700 to $3,500. Because the subject lacks a documented mechanical overhaul (a $300–$600 hidden cost) and the original 'Beads of Rice' steel bracelet (a $300–$500 premium), the FMV appropriately targets the enthusiast 'watch-only' auction lane.
