Family: 50xBased on Ronda 509
The Ronda 509.24H is a quartz movement with a 24-hour display, based on the 509 caliber from the 50x family. It is manufactured in-house by Ronda and remains in production. The 24-hour display formats the time on a single dial rotation rather than the standard 12-hour cycle, distinguishing it from the base 509 movement.
