The type of balance with four particular weights is still used in marine chronometers. Due to accurate adjustment of its parts this solid structure provides precise movement with almost no significant time deviations, which is highly appreciated in modern seafaring. Our minuscule balance possesses all those qualities to provide our chronometers with the highest accuracy. The four flywheels not only gain the visual accent but also make such a filigreed watch balance design possible as well as comfortable repeat adjustment of the centre of gravity.
