70s vintage watch mens Grana Certina T+C town and country automatic 25-651M

Before the world knew the name Certina, there was Grana. Founded in 1888 by the Kurth Brothers (Kurth Frères) in Grenchen Switzerland (The name 'Grana' is a short for Granacus, the Latin for Grenchen) , Grana was the prestigious foundation of what would later become the iconic Certina brand in 1939. Known for their uncompromising Swiss engineering and high-quality in-house movements, Grana watches are today highly sought after by collectors as rare examples of early 20th-century horological excellence.
