The Pure Classic uses IWC’s Caliber 59060, which beats at 28,800 vph and runs in 30 jewels. The balance is adjusted via four gold screws. The balance spring has a Breguet terminal curve. IWC first introduced the manual-winding 59000 series, with its 8-day power reserve, in 2011. The IWC Portofino Hand-Wound Pure Classic has a rose-gold case with a diameter of 43.5 mm. It is 12 mm thick. It comes on a brown alligator leather strap with a pin buckle. All straps for the Portofino Hand-Wound collection are made by the Italian haut de gamme shoemaker Santoni. They have a distinctive orange leather lining.
IWC’s Portofino family dates back to the late 1970s. Since then, it has expanded to include a number of complications, including moon-phase and, last year, big date. The Pure Classic shown here, in rose gold, costs $19,900. In addition, there is a stainless-steel version on a black strap. It costs $10,400. The Portofino Hand-Wound Pure Classic will be available through IWC boutiques.
