IWC caliber 32110
|Hands:||Hours, Minutes, Seconds|
With the 32000-calibre family, IWC expands its range of automatic in-house 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 power reserve. In addition, the long service life of the mechanical components has been increased by newly developed lubricants.
