Vintage 1950s Zaria (Заря) 16 Jewels women's Mechanical Watch, tested & working

vintage Zaria (Заря) women's wristwatch, a well-known brand produced by the Penza Watch Factory in the former Soviet Union. The dial features the Cyrillic text "16 КАМНЕЙ," which translates to 16 jewels—a reference to the synthetic rubies used as bearings in the mechanical movement to reduce friction and improve accuracy.

Brand Meaning: "Zaria" (Заря) means "Dawn" in Russian.
Manufacturing: Produced at the Penza Watch Factory, which specialized in small-caliber movements for women's watches starting in the 1930s.
Era: This specific rectangular style with 16 jewels is characteristic of the 1950s.
Around 1964, the factory unified several different brands (like Aurora and Vesna) under the single "Zaria" trademark.
Movement: It is a manual-wind mechanical watch, meaning it requires periodic hand-winding and does not use a battery.

This watch is tested and fully working. It keeps accurate time.
