The Peseux caliber 320 was produced in Switzerland. This movement can be found with or without shock protection. Other variations also exist depending on when it was manufactured.

The movement pictured above is from a vintage Pontiac watch. According to this page, Pontiac watches were launched in Belgium in 1932:

Alain De Nys fell into the world of timepieces when he was young. This timekeeping enthusiast inherited a passion for watch-making from his mother, who in turn inherited it from her father. In 1932,the grand father of Alain De Nys, Ali Kinsbergen, launched the famous Pontiac brand in Belgium..
