The next challenge for IWC watchmakers was to develop a simpler, basic movement with only time and date functions. From an engineering perspective, that approaches reinventing the wheel, since there are many good basic movements made in Switzerland. Again, the idea was to produce an extraordinarily accurate and sturdy movement.
The end result is now the IWC calibre 32 movement family and its first example is calibre 32110. It’s a mechanical movement with automatic bi-directional winding, dispensing with the more complex Pellaton winding in favor of a traditional system.
This movement, like many basic movements, features 21 jewels and operates at a frequency of 28,800 half-beats per hour. It has several distinctive features, including a power reserve of 72 hours, hacking center seconds and, especially noteworthy, an anchor wheel made from silicon. All is included in a movement with a thin height of 4.2 mm and a 28.2 mm width.
