Browse 32 live Omega auctionsThe Omega 165.008 is a steel, no-date Seamaster De Ville from 1966-1968, built around the ultra-thin automatic caliber 711. Its 34 mm case, straight lugs and restrained dial put the emphasis on proportion rather than complication. Some examples are signed De Ville, while others are presented as Seamaster De Ville, so the complete watch matters more than one line of dial text.
The real buying decision sits between dial preservation and dial character. A clean silver linen dial gives this reference texture without adding visual weight, while a silver sunburst dial can develop heavy spotting across the entire surface. Take the cleaner original dial over a more dramatic damaged one, and take defined straight lugs over a case polished until their edges have softened.

What it was built for
The 165.008 belongs to Omega's 1966-1968 no-date dress-watch period. Caliber 711 keeps the automatic movement thin, while applied indices and stick hands preserve an uncluttered display. At 34 mm excluding the crown, the watch wears compactly and slips under a cuff without needing a large bezel or date aperture to create presence.
Stainless steel and straight lugs give the small case a clear outline. Black inserts in the hands and dark applied markers can strengthen contrast on silver dials, especially against the linen texture. This is not the Omega to buy for complications or oversized proportions. It works as a restrained daily dress watch whose appeal depends on the dial remaining legible and the case retaining its geometry.
Where the value sits
A refinished dial costs more here than softened case edges or an uncertain service history because the sparse no-date layout leaves nowhere for incorrect printing to hide. Between two otherwise comparable watches, the clean silver linen dial deserves the premium over a sunburst dial with prominent spotting. Texture is useful only when the underlying surface and printed text remain intact.
Case definition creates the next meaningful spread. Straight lugs should still read as straight, not rounded into soft ends by repeated polishing, and the Seahorse medallion should remain sharply defined rather than flattened. Applied indices, the Omega logo and stick hands must agree in finish and condition. Heavy dial spotting is damage, not patina, even when distributed evenly, while hand oxidation breaks the controlled contrast that makes this reference work.
Dating and serials
Known 165.008 examples place the reference from 1966 through 1968. Omega serial guidance is approximate within one to three years, so a serial can support a date but cannot establish the watch by itself. The caliber, 34 mm steel case, dial layout and caseback details must make sense together. Service history is often unknown, and without documentation the watch itself cannot establish when the movement was last maintained.

Dating data comes from our decoder tables; treat years as approximate.
What to check before you buy
- Dial and furniture: Correct handled examples use a silver no-date dial in sunburst or linen finish, with applied indices and an applied Omega logo. Crisp printing matters; newly uniform paint over a previously damaged surface indicates a redial, not a service dial.
- Movement agreement: The movement should be the automatic Omega caliber 711 with 24 jewels. Its presence supports the reference, but matching caliber alone cannot rule out a married watch or a franken assembled from parts that did not ship together.
- Case geometry: The stainless-steel case measures 34 mm excluding the crown and uses straight lugs. Rounded or mushy lug ends indicate metal removed by polishing, while a sharply defined Seahorse medallion supports better caseback preservation.
- Hands and dial condition: Known configurations use stick hands, including black-insert or black-finished forms that correspond with dark dial furniture. Oxidation, mismatched finishes or hands that conflict with the indices require scrutiny for later replacement.
