Omega De Ville Ref. 111.071 Wristwatch

Partially verified

This is a vintage men's Omega De Ville square wristwatch, reference 111.071. The seller dates the piece to 1970, though the listing metadata also lists 1960 as date of manufacture. The watch features a square gold faceted case measuring 25 mm across, housing an Omega Calibre 620 manually wound movement reported as fully serviced. The square dial features applied baton hour markers, baton hands, the applied Omega emblem below 12 o'clock, and 'DE VILLE' above 6 o'clock. The watch is fitted to an attractive brown leather strap.

Object description

Dial and Physical Characteristics

Direct observation of the front reveals a light cream-toned square dial configured with applied baton hour indices and a two-hand layout. Printed markings include the applied Omega emblem and brand lettering beneath the 12 o'clock marker, "DE VILLE" above the 6 o'clock marker, and "SWISS MADE" along the lower edge.

The timepiece is fitted with an "attractive brown leather strap", which exhibits a textured surface finish paired with tone-on-tone edge stitching. The vendor describes the case as a "25mm square mens Omega De Ville watch (ref-111.071) in a Gold faceted case".

Evidence for this section
  • “Light cream-toned dial with applied baton indices and matching two-hand layout”
  • “attractive brown leather strap”
  • “25mm square mens Omega De Ville watch (ref-111.071) in a Gold faceted case”

Mechanism and Internal Markings

The seller reports that the "manually wound movement has been fully serviced and is the excellent Calibre 620".

Because no movement or interior caseback photographs are provided in the listing, this calibre designation, jewel count, internal reference stampings, and physical condition cannot be independently verified from the available documentation.

Evidence for this section
  • “manually wound movement has been fully serviced and is the excellent Calibre 620”

Dating and Source Inconsistencies

The listing provides contradictory chronological data across its text and specification fields. The headline and item description assert that it is "An excellent vintage watch from 1970", while the dedicated metadata block specifies "Date of manufacture : 1960" and categorises the era under "Period 19th Century".

Without an accessible serial number from the movement or caseback, the precise production date within the 1960s or 1970s remains unconfirmed.

Evidence for this section
  • “An excellent vintage watch from 1970”
  • “Date of manufacture : 1960”
  • “Period 19th Century”

Open research questions

  • What is the serial number engraved on the Calibre 620 movement, and what exact manufacturing year does it correspond to in Omega factory records?
  • Does the inside of the caseback confirm reference 111.071, and what are the specific metal composition hallmarks (e.g., solid gold versus gold electroplate)?
