Common questions about the IWC Pilot IW377709

How big is the IWC Pilot IW377709?

The case measures 43mm across. 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 IW377709?

Caliber 79320. Power reserve is 44 hours. It beats at 28,800 vph. The movement uses 25 jewels.

Is the IW377709 water resistant?

It is rated to 60 meters, about 197 feet. That covers brief swimming. It is not a dive watch. 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 IW377709 have a nickname?

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