IWC Portofino Hand-Wound Eight Days
IW510107
The Portofino traces its character to 1984, when IWC transformed the language of a Lépine moon-phase pocket watch into a large, elegantly restrained wristwatch. Reference IW510107 pays tribute to those origins with an imposing 45 mm case in 18-carat 5N gold, a silver-plated dial and a dark brown Santoni alligator-leather strap. Its hand-wound IWC-manufactured calibre 59210 turns weekly winding into a ritual, storing 192 hours of power and pairing its reserve display with small seconds and a date indication.
