CAL. 59210

Inside the Portofino Hand-Wound Eight Days, the 59210-caliber manufacturing movement marks the time precisely and reliably for 192 hours, that is exactly eight days, before stopping automatically. In reality, the days would be even nine: the one-day reserve serves to guarantee a couple as constant as possible - and therefore regular operation - for the entire autonomy period. Those who own it are therefore always on the safe side by charging the watch once a week. To know the energy still available, just read the indication of the power reserve on the dial which, together with the display of the small seconds and the date, gives life to a dial with a harmonious layout. The racket-less balance with a frequency of 28 800 vibrations per hour contributes to high running precision, just like the Breguet spiral, curved according to the dictates of the ancient watchmaking tradition. The timepiece features a steel case, a silvered dial and solid gold hour markers. Equipped with a transparent sapphire crystal case back, it is combined with a Santoni brown alligator leather strap.
