Ling,
This was asked and answered in the interview.
IWC make ladies watches but they are NOT small.....more mid-sized. They had Da Vinci ladies from the start but NOT publicised. That is the real question - why not publicised?
Generally, IWC agrees that the product range is tilted to men (Pilots, Portuguese, etc) and their advertising in the past also played on this: "Engineered for Men". But their ladies watches will not be cissy either so they have quite large ladies watches.....fitting with current trend.
Regards,
MTF
