IW5034-01Ref

To mark the 75th anniversary of the Portugieser in 2015, IWC overhauled much of the collection with new models and updates. The 2015 Perpetual Calendar features a redesigned case, dial, and arched glass, while its automatic movement now includes twin barrels for a 7-day power reserve and the signature Kurt Klaus-designed perpetual calendar module. Reference IW5034-01 is crafted in white gold with a blue dial and a black Santoni alligator strap.
