The Caliber 2121 is a derivative of the Caliber 2120, adding an aperture-type date display while maintaining an ultra-slim profile of just 3.05mm. Like its predecessor, it was originally created by Jaeger-LeCoultre and used by multiple prestigious manufacturers. The movement powered Royal Oak models with date function for decades. Replaced by the Caliber 7121 in 2022.
