The A. Schild caliber AS 1220 was introduced in the 1940s. You will often see this movement rebranded under other names, or simply as AS 1220. The AS stands for A. Schild. The movement pictured was found in a vintage Regalis dress watch. It is unsigned.
You will notice the triangle cut-out in the main bridge. The anti-shock system has not been clearly identified, but may be Monorex or Simrex.
