Cal. 69370 (and similar 69375 and 69380) is a midrange in-house automatic chronograph movement produced by IWC since 2016.


The 69000 calibre family is similar in architecture to the IWC 79320 and IWC 75320 which were based on the popular Valjoux 7750 series. IWC greatly modified the movement, however, including implementing a column wheel system rather than the cam-based 7750. The Cal. 69000 series can properly be called an in-house movement, which enhances the reputation of the company's watches.

Although it features bi-directional pawl winding, it is a "push-pull" design like the Seiko magic lever system rather than IWC's Pellaton system. This makes the 69000 calibres more affordable than the IWC 89000 family.

Cal. 69370 is a three-register design with a date window. It features small seconds at 6:00 rather than 9:00 as on the Cal. 75320/Cal. 79320, which it replaces. This movement was only used in a few special edition watches in 2016 and early 2017.

The full-production of this movement is Cal. 69375. This is used in a wide variety of Ref. 3808 Ingenieur Chronograph models since 2017.

The similar 69380 adds a day window at 3:00 to the Cal. 69375.
