Shinola ARGONITE-515-24H

The Shinola Argonite 515.24H is a quartz movement assembled in the USA using a Ronda 515.24H base with Swiss and other imported parts. It features a GMT complication and includes a battery-saving mechanism that reduces power consumption by approximately 70% when the crown is pulled out. The movement uses a CR1216 battery, operates at 32,768 Hz, and maintains accuracy within 20 seconds per month with a single jewel. The Argonite 515.24H powers Shinola's GMT watches, including the Rambler GMT.
