Powering the ZM 2 is the meticulously crafted LH-02 calibre, designed specifically for Leica. Our innovative approach to watchmaking has resulted in the introduction of new functions and an innovative interpretation of traditional complications: the patented push-crown with seconds reset, the movement status display, the unique power reserve, and the day/night indicator. 

Exclusive to the ZM 2 is a 12-hour internal bezel for the seamless tracking of a second time zone via the single-hour hand. This simplistic implementation and combination of features not only enhances the watch's utility, but also showcases the meticulous attention to detail and user-focused design.
