Team,
Not so common here, this Omega DeVille CoAxial, powered by the Omega movement 3313.
This movement comes has a lot of technology: Vertical coupling, column wheel, free sprung balance and a co-axial escapement.
When it was released, it go a very bad reputation (chronograph reset issues) and despite of being corrected by Omega, this tainted reputation stays, thanks to search engines (Just Google "Omega 3313 issues" to see).
I had several watches with this movement and no issues.
Beautiful IMHO:
