IWC Portofino Perpetual Calendar Reference 3541: An Oft-Forgotten Eternal Gem – Reprise
IWC is a brand with a rich history, and it is in the fortunate position that each of its collections has an almost equal share in building this history. The Da Vinci Perpetual Calendar, developed by IWC’s master watchmaker Kurt Klaus, was a horological revolution. And from it came this elegant Portofino variation of the 1990s.
