Common questions about the IWC Portugieser IW371446

How big is the IWC Portugieser IW371446?

The case measures 41mm across and 12.3mm thick, with a 20mm lug width. Case material: Steel. 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 IW371446?

Caliber 69355. Power reserve is 44 hours. It beats at 28,800 vph.

Is the IW371446 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 IW371446 have a nickname?

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