The Saintis brand was a 1980s export trademark most likely intended for the French market. The brand may have been a subsidiary of the French company Slava SA. This brand used movements from Poljot​ (2616.2H) and Molnija (3602), among possible others. Watches bearing the Saintis brand were typically identical to domestic production models aside from the brand on the dial.
