The following link provides some details of patents held by IWC, I'll add more as I become aware of additional material.

IWC Patents

Cheers from the cellar

Thanks Greg for this valuable source of information.

Stellar research Greg. Excellent contribution to the knowledge of IWC's history.

Greg --a very important contribution! Thank you hugely.

It is always great to see new research from the Cellar! Thank you Greg for providing this interesting info!

It stops in 2000, on the UTC. Didn't IWC apply for patents after 2000? My gut feeling tells me there must be a few in recent times, like about the constant force tourbillon or parts of the Siderale.

Kind regards,
Paul

Thank you Greg,

in general for your very informative website, for the effort to keep it up to date and for this very interesting current information.

There are many after 2000. I just sent several to Greg to include, if he desires.

Very interesting, thank you, Greg!
