The Frederique Constant caliber FC-220 is a 2-hander quartz movement found in the brand’s Classics line of watches.

Base Caliber:

Although Frederique Constant is owned by Citizen Watch, the FC-220 uses Ronda movements as a base.

Frederique Constant creates unnecessary caliber confusion with the FC-220 by using different movements as the base depending on the watch model. According to Caliber Corner’s Caliber Designation Guidelines, a different brand caliber number should be used if the base caliber is different.
