L132.1

The manufacture calibre L132.1 is a new movement that differs significantly from the 2004 Double Split's L001.1 calibre. By moving the power-reserve indicator downward, more room was created for the rattrapante hour counter at the top of the dial, allowing engineers to fit the extra components without increasing the case size. The sapphire-crystal caseback showcases the movement's 567 parts, including 46 jewels, and its intricate mechanical operation, all within a 30.6mm by 9.4mm frame.
