The Omega De Ville Chronograph Ref. 146.017 is one of the most distinctive and underappreciated chronographs in Omega’s vintage catalogue. Produced for a very short period between 1969 and 1970, this reference was part of Omega’s move to give the De Ville line sportier capabilities without sacrificing its dress-watch elegance.
At the heart of the watch is the manual-wind Calibre 930 — a Lemania-based cam-switched chronograph movement. It is notable for its unusual date-at-9 placement, a feature shared by very few chronographs of the era, giving the dial a balanced yet unconventional layout. The Cal. 930 is known for its reliability, serviceability, and smooth operation, making it a favourite among vintage Omega enthusiasts.
This example features a clean silver dial with a tachymetre scale, chronograph minutes at 3 o’clock, and running seconds/date at 9 o’clock. The original Omega flat-link 1425 bracelet adds period-correct charm, making it a complete and authentic vintage package.
Movement History
The Omega Calibre 930 was introduced in the late 1960s as part of the brand’s expansion of its chronograph range. Based on the Lemania 3872, it replaced the column-wheel architecture of earlier calibres with a cam-and-lever switching system, making it easier to service. What sets the 930 apart is its unusual combination of chronograph and date-at-9 — a complication placement that was rare at the time and remains visually distinctive today. The Cal. 930 was only produced in limited quantities before being phased out, adding to its collectability.

Why Buy This Watch
Short Production Run: The 146.017 was only made for a brief period, making it far rarer than contemporary Speedmasters or Seamasters.
Historic Movement: The Cal. 930 is part of Omega’s respected Lemania-powered chronograph family, offering mechanical pedigree and the distinctive date-at-9 complication.
Collector Appeal: The De Ville Chronograph is a left-field choice — less common on the market and more distinctive in design than most vintage Omegas.
Complete and Authentic: With its original flat-link bracelet, this example offers period-correct completeness rarely found today.
For collectors, this is an opportunity to acquire a seldom-seen piece of Omega history that blends sporty chronograph capability with the refined aesthetic of the De Ville line — a combination unlikely to be repeated in the same way.
