A beautifully faceted crystal gives this vintage Omega De Ville its distinctive character. Its sharply bevelled edges catch the light around a restrained charcoal-grey dial, creating depth and shifting reflections while leaving the slender hands and four elongated hour markers clearly defined.

Known as the “Emerald” or “Emeraude,” reference 511.0378 captures the jewellery-inspired experimentation of Omega’s 1970s designs. Its geometric lines reflect the influence of Andrew Grima’s work with the brand, bringing a sculptural quality to a compact, understated dress watch.

The clipped-corner rectangular case measures 25 × 35 mm, offering elegant unisex proportions. A black textured leather strap complements the dial and keeps attention on the striking crystal.
