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.
