A true icon of late-70s watchmaking, this Eterna Delirium II is not just elegant — it’s a technical legend and a historic breakthrough in ultra-thin watch design.
When it was launched, the Delirium line made headlines as the world’s thinnest watch, a record-breaking feat that redefined what was possible in Swiss horology.

Built around the revolutionary ESA 999.001 quartz calibre — only 1.2 mm thick — and integrated directly into the case, this watch achieved an incredible 2 mm total thickness.
It’s the perfect blend of innovation, precision, and pure style.
Its rectangular 18 k gold case, decorated with a delicate guilloché texture, pairs beautifully with the minimalist white dial and Roman numerals.
Everything about it screams refinement — right down to the original black leather strap and signed Eterna gold buckle.

Why it’s special:

Because this isn’t just a watch — it’s a piece of horological history.
Light as air, razor-thin, and effortlessly chic, the Delirium II captures the spirit of an era when Swiss watchmakers pushed boundaries just for the thrill of it.
