Description
This Omega De Ville is a quintessential example of mid-century ladies' jewelry-style horology. Before the quartz crisis fully took hold, Omega focused on ultra-thin mechanical movements that allowed for these incredibly petite and elegant proportions. The watch wears more like a fine piece of jewelry than a traditional timepiece, featuring a mesh bracelet that tapers beautifully to the wrist. It represents a time when Omega's dress watches were the height of sophisticated fashion.
Key Features
Integrated mesh bracelet for a seamless 'cuff' look, ultra-slim manual wind caliber, and the minimalist 'time-only' rectangular dial. The hallmark of this specific model is the texture of the bracelet transitioning into the head of the watch.
Dial Description
Silver or champagne linen/brushed dial. Features applied gold baton indices and matching minimalist baton hands. No seconds hand or date to maintain a clean, formal aesthetic. Printed Omega logo and 'Swiss Made' at 6 o'clock.
Case Material
18k or 14k Yellow Gold (or Gold-Plated/Plaque depending on the specific reference). Polished finish with an integrated bracelet design.

Likely mineral glass or hesaltite/acrylic, flat or slightly faceted. Appears clear in the photo with minor age-related wear.
Bezel Details
Fixed, polished yellow gold bezel, integrated seamlessly into the rectangular case structure. Minimalist design.
Crown & Pushers
Small, push-pull gold crown at 3 o'clock, likely signed with the Omega Greek letter crest. Designed to be discreet.
Bracelet or Strap
Integrated tapered mesh (Milanese) bracelet in matching yellow gold or gold-plated finish. Features a jewelry-style clasp with the Omega logo visible on the buckle.
Caseback Details
Solid, snap-on case back. Typically plain or with very light engravings of the 'De Ville' logo or simple gold hallmarks on the interior.

Manual/Hand-wound mechanical movement. Likely an Omega Caliber 620 or 625, known for their ultra-slim profiles. Typically 17 jewels, 19,800 or 21,600 bph.
Water Resistance
Not water resistant. No practical protection against moisture; users should avoid splashes and humidity due to the age of the gaskets.
Origin & Provenance
Swiss Made. Manufactured in Switzerland, likely in Bienne or Geneva. Employs a high-quality in-house mechanical caliber.
Age Estimate
Circa 1968-1975. The design language, logo style, and integrated bracelet are characteristic of early De Ville collections from this period.
Cultural Significance
Reflects the 1970s shift toward watches as fashion accessories. This style of integrated bracelet watch was popularized by icons like Jacqueline Kennedy Onassis, who favored the slim Cartier Tank but wore similar integrated designs.
Condition Notes
Overall Very Good. The dial appears clean. The gold finish shows light surface scratches consistent with age. The bracelet appears straight without significant kinks in the mesh. Crown and clasp appear functional.
Value Estimate
$300 - $600 USD if gold-plated; $1,200 - $2,500+ if solid 18k gold. Value is heavily dependent on the metal content and the presence of original Omega signatures on the crown and crystal.
Care & Maintenance
Mechanical movements of this age should be serviced every 5-7 years. The mesh bracelet should be cleaned with a soft brush to remove skin oils. Avoid water entirely as vintage dress watches have negligible water resistance.
