Apart from familiar hallmarks such as the twin mainspring barrel with a power reserve of 72 houres, the 2015 calibre L121.1 has an escapement featuring a balance wheel with eccentric poising weights as well as a freely oscillating balance spring crafted in-house. Beneath the hand-engraved balance cock, the balance beats at a frequency of 21,600 semi-oscillations per hour and assures high rate accuracy.
