Common questions about the IWC Portugieser IW503301

How big is the IWC Portugieser IW503301?

The case measures 44.2mm across. Case material: Rose gold. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

What movement is in the IW503301?

Automatic, IWC Cal. 52610 (Pellaton winding), 7-day power reserve. Power reserve is 168 hours. It beats at 28,800 vph.

Is the IW503301 water resistant?

It is rated to 30 meters, about 98 feet. That covers rain and hand washing. It is not rated for swimming. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Does the IW503301 have a nickname?

Portugieser Perpetual Calendar. Collector nicknames are not official IWC names, but they are what people actually search for and what they are called across a showroom.
