CAL. 59900

The Portofino Hand-Wound Tourbillon Rétrograde presents three interesting complications: the manual winding with 8-day autonomy, the flying tourbillon at «6 o'clock» and the retrograde date indication that extends from «8 o'clock» to «10 o'clock ». The manual caliber 59900 made it possible to integrate a tourbillon with a stop device, which, in turn, allows you to set the time with an accuracy per second. The retrograde date display displays the day of the month analogically on an arched scale. At the end of a 31-day month, the date hand automatically returns to one. In the shorter months or when the watch is not worn for some time, the date can be quickly moved forward until it returns to the first of the month. Set in an 18-carat red gold case, the dial shines in silver tones. The watch is accompanied by a dark brown alligator leather strap from the Santoni luxury manufacture.
