In 2015, IWC updated the Portugieser Perpetual Calendar with an arched crystal, refined case and dial aesthetics, and a movement featuring twin barrels, a 7-day power reserve, and the signature Kurt Klaus perpetual calendar module. Added in 2020, the reference IW503312 features an 'Armor' red gold case paired with a blue dial.
