One of the technical hallmarks of the L094.1 movement is the refined arrangement of two wheel trains that allows constant-force generation and the seconds jump to interact. The result is a constant amplitude across the entire power-reserve range of up to 42 hours. Superior rate accuracy is guaranteed as well thanks to the balance wheel with eccentric poising weights and the free-sprung balance spring crafted in-house.
