Thank you very much for viewing this listing!

I am offering a vintage watch from the "Geneve" series by OMEGA, a premier Swiss luxury watch brand.

Omega's "Ladymatic" is a self-winding (automatic) mechanical watch for women that debuted in 1955.
Unlike the manual-wind watches that were the norm at the time, it was launched as a groundbreaking model capable of automatically winding the mainspring—even on a woman's wrist.
The "Cal. 671" is a renowned movement used in ladies' models, including the Ladymatic, from approximately 1961 to 1971.
* Production Era: Circa 1961–1971
* Features: A high-grade specification utilizing 24 rubies (jewels used to prevent wear on pivots, etc.); it packs advanced technology into a compact size.
* Vibration Rate: 19,800 vibrations per hour (approx. 2.75 Hz).

The Cal. 671 features intricate components required to drive the mechanical watch;
it stands as a testament to Omega's superior technical prowess at the time
and remains highly valued in the antique watch market today.

If you have been looking for a piece like this, please consider taking advantage of this opportunity.
