AS Calibers

AS is the caliber prefix for A. Schild SA, one of the largest and most prolific Swiss ebauche manufacturers of the 20th century, founded in 1896 in Grenchen (canton of Solothurn) following a split from the Eterna factory. The firm grew rapidly into a dominant force in Swiss movement supply, producing calibers across the full range from ladies' to pocket watch sizes.

A. Schild was a founding member of Ebauches SA in 1926 alongside A. Michel (AM) and FHF, and its AS-prefix movements were used by hundreds of Swiss and international watch brands ā€” from mass-market to mid-range labels. The AS 1002 and related calibers are among the most widely encountered Swiss movements in vintage watches of the 1950sā€“70s. The quartz crisis devastated the firm; by 1979 it was merged with ETA (also of Grenchen) and ultimately absorbed into the Swatch Group. Collectors working on Swiss vintage watches will encounter AS movements constantly.
