IWC Caliber 32150

The IWC caliber 32150 is an automatic triple-date moonphase movement in the IWC 32000 family of watch calibers.

Although you will see many of the blogs labeling the 32150 as an in-house movement, this movement is considered to be a manufacture movement, produced for IWC by Manufacture Horlogère ValFleurier.

In IWC’s own words:

“With the 32000-calibre family, IWC expands its range of IWC-manufactured automatic movements. For these rugged and reliable movements, and for the first time ever, IWC has used components made of silicon. The escape wheel and pallet lever are made of this incredibly wear-resistant material. A bidirectional pawl-winding system supplies the energy required by the movement. Similarly to a Pellaton automatic winding system, it winds the mainspring when the rotor is moving in either direction. Thanks to advances in movement technology, the 32000-calibre family offers a 72-hour to 120-hour power reserve. In addition, the long service life of the mechanical components has been increased by newly developed lubricants.” –Source
