The Portugieser Automatic, a flagship model particularly true to the 1930s design, has undergone certain essentially technical modifications. The IWC constructors have further perfected its movement, notably by integrating ceramic elements into the bidirectional Pellaton winding system. The new Calibre 52010 also benefits from the efficiency of twin barrels instead of just one to guarantee a seven-day power reserve. The slimmed-down, openworked rotor also provides a broader view of the mechanisms visible through the transparent sapphire crystal back. The Portugieser comes in five different versions.
