The new Leica ZM Monochrom Edition watches take inspiration from the release of the latest Leica M11 Monochrom camera and honors the most fundamental principles of black and white photography: contrast and light. The Leica ZM Monochrom Edition watch collection consists of two models, both with mechanical manual wound movement developed and produced in-house. The Leica ZM 1 and Leica ZM 2 —a GMT Dual Time Zone—, are now available in the new Monochrom Edition.
