IWC Pilot's Watch TOP GUN IW389101

The case measures 44.5mm across and 15.7mm thick, with a 21mm lug width. Case material: Black zirconium-oxide ceramic with titanium caseback. 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.

Automatic chronograph, IWC Cal. 69380 (column-wheel, in-house), approx. 46-hour power reserve. Power reserve is 46 hours. It beats at 28,800 vph. The movement uses 33 jewels.

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.

IWC produced this reference from 2019 to the present day. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.
