AI Appraisal Estimate

This item is a vintage Omega De Ville watch component, consisting of the dial, hands, and internal movement, currently removed from its original case. The standout feature is the circular dial crafted from genuine Lapis Lazuli, exhibiting a deep ultramarine blue coloration with characteristic natural inclusions that may include golden pyrite flecks and white calcite streaks. The dial face is minimally styled without hour markers, featuring the Omega logo and brand name printed in white at the 12 o'clock position, 'DE VILLE' above the 6 o'clock position, and 'SWISS MADE' at the very bottom. It is fitted with two simple, baton-style silver-toned hands (hours and minutes). The winding crown remains attached to the movement stem on the right side. Structurally, the dial is held within a slim metal ring which appears to be yellow gold or gold-plated, showing some minor edge wear. The condition of the stone dial appears stable, though there are visible white particulates or possible surface oxidation on the hands and at the center arbor. The movement is reported to be in working condition, which is a significant quality indicator for a mechanical piece of this age. Based on the style and typography, this piece likely dates from the 1970s, a period when Omega frequently used hardstone dials in their De Ville and Geneve luxury lines.

Upon my examination of this Omega De Ville movement and lapis lazuli dial, I find the piece to be a distinctive example of 1970s horological luxury. The use of genuine hardstone dials was a hallmark of Omega's high-end artistry during this era. The deep ultramarine blue of the lapis is consistent with high-grade specimens, showing the desirable pyrite inclusions often sought by collectors. While the movement is reported to be working, the visible particulates on the handset and center arbor suggest a need for a professional service to ensure long-term viability. The absence of the original precious metal case significantly impacts the total value, as these components are currently viewed as replacement parts or 'project' pieces for restorers. However, genuine, uncracked lapis dials are increasingly rare and hold strong individual value. Market comparables for loose 1970s Omega stone dials range widely, but a functional movement adds a premium. Authenticity appears consistent with Omega’s manufacturing standards of the period, particularly the typography and crown style. Final authentication is limited by the digital format; a physical inspection is required to verify the movement's caliber number, serial range, and the structural integrity of the stone under magnification to check for hairline fractures not visible here. Scientific testing of the metal ring's gold content and provenance documentation would further solidify this valuation.
