Heritage & Design
The Omega Constellation line has long stood as the brand’s flagship of precision and prestige. In the late 1960s and early 1970s, Omega introduced the Ellipse and Tank-inspired designs, merging avant-garde geometry with high-end materials. The result is this extraordinary Ref. 153.0034 — a solid 18K yellow gold creation featuring a distinct oval tank-style case, notable for its “OM” signed dial, indicating solid gold dial markers (“Or Massif”).
Measuring 28mm by 36mm, the Ellipse case is elegantly proportioned, offering both visual presence and wrist comfort. The minimalist design is enhanced by the warm, lustrous tone of its unpolished gold surfaces and a perfectly balanced dial layout. This is Omega design at its most architectural and pure.
