Calibre 98000 is a family of classic watch movements produced by IWC since the 1930s.


IWC introduced the hunter pocket watch movement Cal. 98, in the 1930s. But it became well known as the movement inside the famous Portugieser wrist watches, produced in limited numbers that decade.

IWC brought back the movement as Cal. 982 in 1977 for the "German Edition" Portugieser, produced until 1981. In 1993, IWC revived the classic movement as Cal. 9828. This modern development added shock resistance to the balance.

Cal. 98290 is a modern incarnation of the classic Cal. 98. It features the elongated adjustment index of early pocket watch movements along with a modern Glucydur balance.
