The Caliber 4309 is essentially the no-date version of the Caliber 4302. With 225 total components (versus 257 in the 4302), the lack of a calendar system results in a reduced component count. AP touts the simplicity of the 4302, and the 4309 takes it even further as a true no-date movement. Powers select Code 11.59 and Royal Oak models.
