Universal Genève Calibre 215

Calibre 215 is an automatic movement introduced by Universal Genève in 1956 for the Polerouter collection. It operates at 28,800 vph and represents an evolution of the earlier 138 SS caliber, featuring Microtor technology. The in-house movement was produced in several variants, including date and non-date versions, with specific designations for the US market. This caliber powered the Polerouter line and has since been discontinued.
