From 1968, this Omega carries the restrained elegance of late‑60s watchmaking with the distinctive presence of an emerald‑cut sapphire crystal. The clean, architectural silhouette implied by the crystal shape speaks to a period when case and glass were composed to read as a single design gesture. As an Omega product, it belongs to a long tradition of reliable Swiss movements and thoughtful execution, even when specifics are not recorded. For the modern collector it offers a refined example of period design and provenance from the “collection of Andrew Grim.”
