A one-piece case for Omega’s 1960s dress watch
This Omega Seamaster De Ville reference 135.020 can be worn equally well by a man or a woman, with a 34.5mm gold cap case — a layer of gold bonded over a steel base, noticeably thicker than electroplating. The lugs are long and curve toward the wrist, while the bezel is narrow and domed. At 40mm Lug-to-lug and 9mm thick, the piece has presence on the wrist without excess.
Its construction is monocoque: the case is machined from a single piece, with no removable caseback. The movement is inserted from the front, after removing the Crystal. Omega used this method to improve resistance to dust and moisture, at a time when screw-down casebacks were reaching their limits. This explains the complete absence of a separation line along the sides.
The silvered dial features a sunburst satin finish radiating from the center, causing the tone to shift with the angle of the wrist. The applied baton hour markers are filled with black lacquer, as are the golden hands, giving the display clear contrast without resorting to numerals. This dial is not the one fitted at the factory when the watch left production: it is most likely an Omega service dial, fitted during a service, though we cannot state this with certainty. We prefer to point this out rather than suggest it is an original dial.
The De Ville line was born within the Seamaster collection before breaking away to become a full-fledged range in 1967. These transitional pieces, signed with both names, correspond to the moment when Omega first distinguished its dress production from its sports production. The hand-wound movement powering it belongs to the caliber 600 family, developed in the early 1960s for the maison’s ultra-thin watches.
Three points to note
- Monocoque Case — machined from a single piece, with no removable caseback, and with a movement inserted from the front: no separation line along the sides.
- Gold cap construction — a layer of gold bonded over steel, far thicker than electroplating and more resistant in wear.
- Likely service dial — not fitted at the factory when the watch left production, it offers clear, unaltered legibility at a lower price than an example with its original dial.
Why choose a vintage Omega watch?
Buying a vintage Omega watch rather than a new model means gaining access to a historic Swiss manufacture on a budget wholly unrelated to boutique pricing, with pieces whose construction has already stood the test of six decades. The manual calibers from this period are among the easiest vintage mechanical watches to maintain: their architecture is well documented and spare parts remain accessible.
The Seamaster De Ville holds a precise place among vintage watches for men and women: its 34.5mm diameter makes it a vintage dress watch that can be worn equally by both, in a format long considered too discreet and which now matches the dominant demand on the pre-owned market.
Like all our pre-owned Omega watches , this one has been opened and inspected by our watchmakers: verification of the calibre and its consistency with the reference, checking of the serial number, examination of the dial, hands, and case. Each vintage luxury watch we offer comes with an invoice Atelier Victor serving as a certificate, a twelve-month mechanical warranty, and lifetime guaranteed authenticity.

Condition and warranty
- Overall condition: Good state of preservation for a piece over sixty years old. The dial is not the one fitted when it left the factory: it is most likely an Omega service dial, although we cannot state this with certainty. Its appearance is impeccable, and the applied indices and hands are all in place. The gold layer on the case shows visible wear around the bezel, where the steel appears in places, as shown in our photographs. The Crystal plexi bears fine signs of wear in the form of scratches (7/10).

Frequently asked questions
Is the dial the original one?
No. It is most likely an Omega service dial, meaning a part supplied by the manufacture and fitted during a service, although we cannot state this with certainty — only an inspection of the back of the dial would make it possible to decide between this hypothesis and a restoration carried out by a third party. The distinction matters to a collector, as a service dial remains a manufacture part. In both cases, neither legibility nor operation is affected, and the price of this piece reflects that.
What is a monocoque case?
This is a case machined from a single piece, with no removable case back. The movement is inserted from the front, after removing the Crystal, which explains the absence of any separation line on the sides. Omega used this process to improve resistance to dust and moisture. In practice, servicing requires a watchmaker equipped to open it from the front, but the operation remains common and presents no particular difficulty.
What is gold cap construction?
Gold cap consists of applying a layer of gold to a steel case, by soldering or pressing, rather than depositing it through electroplating. The resulting layer is significantly thicker than conventional plating and withstands friction far better. It is an intermediate construction between plating and solid gold, which Omega commonly used on its dress watches of the 1960s.
Why the double signature Seamaster De Ville ?
De Ville was born within the Seamaster collection as its dress variation, before separating from it to become an autonomous line in 1967. Pieces bearing both names therefore correspond to this transitional period, when Omega was distinguishing its de ville production from its sports production for the first time.
Is this piece suitable for a slim or larger wrist?
With a diameter of 34.5mm, a 40mm Lug-to-lug, and a thickness of 9mm, it suits wrists of approximately 15 to 19cm. Its long, curved lugs follow the wrist and reduce the feeling of bulk. This was the standard format for the dress watch of the 1960s, and it has now largely returned to favor. The Lug width measures 18mm.
