Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
Omega De Ville 38 mm Blue 18k sits within Omega's De Ville line, introduced in 1970. It carries the house codes established since 1848 — 18k white gold case, blue "grande tapisserie" dial and in-house manual-winding — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

Brand history
Omega has spent more than 178 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Speedmaster, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis Brandt established Omega in 1848, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Omega calibre produced today.
