Shinola ARGOMATIC-R-150

The Argomatic R-150 is an automatic movement manufactured by Shinola in Switzerland. Based on the Ronda R150, it operates at 28,800 vph with 25 jewels and provides approximately 40 hours of power reserve when fully wound. The movement features hand-winding capability and Incabloc shock protection. It was Shinola's first branded automatic movement, used primarily in the Lake Erie Monster before being replaced by the Sellita SW200-1.
