Help in identifying watch

Hi,

Happy New Year!!

Can someone help me to identify the following watch?

Thanks a ton

Nand

This is like no squelette I have seen.
Let's see the back please

Your watch would appear to be a Ref 8211 with a calibre 1857 movement.

Cheers from the cellar

Thank you so much

Very unique and unusual IWC Squelette
