Cal. 89XXX
The core technology of IWC focuses on long power, chronograph, perpetual calendar and tourbillon, since most of in-house movements features those above. Now, cal. 89361, one of core in-house chronograph movement, widely applies to the main collection. An absolute widely-used chronograph movement in all IWC movements. With the functions are added to the basic movement, many complicated movements came out. Cal. 89900 with tourbillon chronograph. Cal. 89630 with four-digit year calendar chronograph.

Cal. 98XXX, manufacture mechanical movement with manual winding. Its basic model is cal. 98300, a revised version of cal. 98295. It’s also called the “Jones Arrow” movement, which applies to IWC Vintage watches in order to honor Florentine Aristo Jones, the U.S. founder of IWC.

IWC has far more movements than those. Due to the replacements of old and new movements, the old models are used rarely, for example, 80000-calibre family. Judging from in-house movements, IWC shows its capability on modifying, developing, processing movements. Cal 69370 and cal. 69375 fill in the gaps of self-made entry level chronograph movements. IWC will release entry level automatic movements with hour, minute and small second hands. Hence, IWC in-house movements will form a strong team.

IWC is a reputable wristwatch manufacturer with good sales. When it comes to IWC, IWC Portugieser Chronograph watch and Portugieser Automatic 7-Days watch occur to our minds. But, I’m going to introduce IWC movements instead of IWC wristwatches. As we all know, the movement determines the value of a watch, and the more advanced the movement is, the more valuable the wristwatch is. IWC watches all have nice appearances, and IWC has kept trying its best to develop in-house movements to break away from supply movements. After all IWC has been fallen behind Rolex, Omega, Panerai on the development of self-made movements.

IWC has made clear that it owns 60% in-house movements, and the rest comes from ETA and Sellita. What’s more, the two companies produce universal movements according to the demands of IWC, even the accuracy of these movements reaches up to 0/+7 error. From the in-house movement project and the new-built watchmaking factory, we know that more and more self-made movements will come out.
