The Omega Seamaster DeVille is a vintage timepiece that was first introduced in 1960. The main difference between the versions is their calibers, but the DeVille has a Unishell case, which is one solid piece and lacks a screw-down case back. This means that you can only service the movement from the front. The DeVille has a wide range of dial designs, most featuring narrow bar indices, though some have numerals or triangular indices
 
Here are some features of the 1954 Omega 14KGF Seamaster DeVille:
Case: Solid 14K gold case that measures approximately 36.5mm (case to crown) x 10mm (high)
Dial: Silver oyster with gold-tone non-numerical hour markers and matching hands
Crown: 14K gold crown and caseback engraved with the Seamaster emblem
Case design: Monocoque design improves water-resistance without tampering with style and design
The DeVille typically features manual or automatic movements, and their design is a nod to the traditional watchmaking ethos of Omega, prioritizing simplicity and elegance. Collectors and enthusiasts often seek these vintage models for their historical value and timeless design.
