The A. Schild 1580 is a self-winding, automatic watch movement that was introduced to the market in the 1950s. You will often see this movement rebranded under other names, or simply as AS 1194. The AS stands for A. Schild. The movement pictured here was found in a vintage Enicar timepiece.
There is also a caliber 1581 variation that adds a date complication.
