IWC Pilot's Watch Mark XVIII IW328201

The case measures 40mm across and 10.8mm thick, with a 20mm lug width. Case material: Stainless steel with soft-iron inner case (anti-magnetic). 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, in-house IWC Cal. 32111 (

It is rated to 100 meters, about 328 feet. That is enough for swimming and snorkeling, but not for scuba diving. 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 2022 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.
